Fix stringFirst/stringLast rollup during ingestion #10332

joykent99 · 2020-08-28T22:08:11Z

Fixes #7243 .

Description

This PR fixes the issues with stringFirst/stringLast rollup during ingestion, based on the suggestions described in #7243. A test is added to trigger the rollup code path for stringFirst/stringLast.

This PR also enables earliest/latest aggregator to operate on these columns during query time.

This is the first time I submitted a patch to Druid. Any comments and suggestions are appreciated!

This changelist adds a test to merge indexes with StringFirst/StringLast aggregator.

The segment-level type for stringFirst/stringLast is SerializablePairLongString, not String. This changelist fixes it.

This changelist allows EarliestLatestAnySqlAggregator to accept COMPLEX type as an operand. For its return type, we set it to VARCHAR, since COMPLEX column is only generated by stringFirst/stringLast during ingestion rollup.

@joykent99 Thanks for the contribution! I haven't looked through the approach yet, but I notice there aren't any integration tests added for this change. Can you add one for the bug reported in #7243. This way we can be sure not to break this feature going forward.

I think you can do this by modifying one of the tests in ITIndexerTest. Consider adding a stringFirst and stringLast aggregation to /indexer/wikipedia_index_task.json and then modifying one of the queries in /indexer/wikipedia_index_queries.json to test that the aggregation is correct.

Thanks @suneet-s for the tip on adding the integration tests. I will work on it and update the PR.

@suneet-s, I have added some integration tests in this PR. It looks like the CI build failed due to license errors. Do you have any suggestions to how to resolve these errors? Thanks.

I re-triggered the job. I've seen it be flaky before, not sure why. Looks like everything is passing now 🎉

I'll try to get some time to review this in the next couple days

I don't fully understand how Combiners work, so I'll need to spend more time thinking about how this might impact other things. But I commented on stuff I have a little bit of a better understanding of.

Can we add these to wikipedia_index_task.json instead. This way we don't need to run another integration test which can be quite slow

You will probably want to do something very similar to #9277

The issue described in #7243 requires a trigger of merging of two index files, which will in turn cause a rollup of two rows. I wasn't able to trigger that in wikipedia_index_task.json. This is why I added a new task to capture this case.

I also added these in wikipedia_index_task.json, which led me to discover the issue with StringFirstAggregatorFactory.combine() below.

wow! Is there a test for this somewhere?

Yes. The existing test case was testing the wrong behavior. The fix to the test is also in this PR.

shouldn't this remain STRING ?

When we specify "stringFirst/stringLast" in ingestion MetricsSpec, the type for the columns stored in segments is OTHER. With STRING type here, the SQL will report an error when trying to call earliest/latest on those columns.

If you have any suggestions on where is a good place to add a test for this, that would be great!

Usually I sql add tests to CalciteQueryTest You can see testEarliestAggregators as an example. You could write a test in here to validate the SQL translation works, but I think you need to update CalciteTests#INDEX_SCHEMA_DIFFERENT_DIM3_M1_TYPES to add an earliest / latest aggregator. Then you should be able to test a SQL test in CalciteQueryTest - hope this helps

@suneet-s Please let me know if you have more comments on this PR. It looks like @gianm also found the issue with StringFirstAggregatorFactory.combine() function, which is what caused the above conflicts. Should I pull in the new changes in the master to my branch, and force push it? Thanks.

suneet-s · 2020-09-08T19:00:14Z

@joykent99 the way I resolve merge conflicts is like this

git fetch upstream
git merge upstream/master
# Resolve merge conflicts manually
# ...
git push origin <branch>

This way you don't need to force push, so the comment history is still referenceable in the PR. I think the change looks good to me, just going to do a once over today and post final comments.

Thanks again for fixing this!

suneet-s

LGTM after resolving merge conflicts.

That's correct -- Long / Double / Float first/last agg still can not be used at ingestion time.

@joykent99 but firstString/lastString should be working fine?

Could you please explain how to use it inside the query? Let's say we added a metric to be lastString aggregator during ingestion time. And this metric has OTHER type:

How can it be queried, something like say SELECT * WHERE test='JarBot'?

Since the data for lastString aggregator stored in segments are in SerializablePair, to get the final result, we issue the query like this:

select <your_grouping_column>, latest(test, 1024)
from wikipedia-test
group by <your_grouping_column>

Native batch range partitioning was only considering the partition dimension value when grouping rows instead of using all of the row's partition values. Thus, for schemas with multiple dimensions, the rollup was overestimated, which would cause too many dimension values to be packed into the same range partition. The resulting segments would then be overly large (and not honor the target or max partition sizes). Main changes: - PartialDimensionDistributionTask: Consider all dimension values when grouping row - RangePartitionMultiPhaseParallelIndexingTest: Regression test by having input with rows that should roll up and rows that should not roll up * Use hadoop & native hash ingestion row group key * Fix nullhandling exception (#10095) Co-authored-by: Atul Mohan <[email protected]> * Make 0.19 brokers compatible with 0.18 router (#10091) * Make brokers backwards compatible In 0.19, Brokers gained the ability to serve segments. To support this change, a `BROKER` ServerType was added to `druid.server.coordination`. Druid nodes prior to this change do not know of this new server type and so they would fail to deserialize this node's announcement. This change makes it so that the broker only announces itself if the segment cache is configured on the broker. It is expected that a Druid admin will only configure the segment cache on the broker once the cluster has been upgraded to a version that supports a broker using the segment cache. * make code nicer * Add tests * Ignore icode coverage for nitialization classes * Revert "Ignore icode coverage for nitialization classes" This reverts commit aeec0c2ac2b07c1b9262e32201913c7194167271. * code review * Correct the position of the double quotation in distinctcount.md file (#10094) ``` "dimensions": "[sample_dim]" ``` should be ``` "dimensions": ["sample_dim"] ``` * QueryCountStatsMonitor can be injected in the Peon (#10092) * QueryCountStatsMonitor can be injected in the Peon This change fixes a dependency injection bug where there is a circular dependency on getting the MonitorScheduler when a user configures the QueryCountStatsMonitor to be used. * fix tests * Actually fix the tests this time * Information schema doc update (#10081) * add docs for IS_JOINABLE and IS_BROADCAST to INFORMATION_SCHEMA docs * fixes * oops * revert noise * missed one * spellbot * Remove payload field from table sys.segment (#9883) * remove payload field from table sys.segments * update doc * fix test * fix CI failure * add necessary fields * fix doc * fix comment * Web console: allow link overrides for docs, and more (#10100) * link overrides * change doc version * fix snapshots * Enabling Static Imports for Unit Testing DSLs (#331) (#9764) * Enabling Static Imports for Unit Testing DSLs (#331) Co-authored-by: mohammadshoaib <[email protected]> * Feature 8885 - Enabling Static Imports for Unit Testing DSLs (#435) * Enabling Static Imports for Unit Testing DSLs * Using suppressions checkstyle to allow static imports only in the UTs Co-authored-by: mohammadshoaib <[email protected]> * Removing the changes in the checkstyle because those are not needed Co-authored-by: mohammadshoaib <[email protected]> * Prevent unknown complex types from breaking DruidSchema refresh (#9422) * Update web address to datasketches.apache.org (#10096) * Join filter pre-analysis simplifications and sanity checks.

Before this change, the web-console would indicate this by changing the text of the button from Run (SQL queries) to Rune (native queries).

(#10119) * Combine InDimFilter, InFilter. There are two motivations: 1. Ensure that when HashJoinSegmentStorageAdapter compares its Filter to the original one, and it is an "in" type, the comparison is by reference and does not need to check deep equality. This is useful when the "in" filter is very large. 2. Simplify things. (There isn't a great reason for the DimFilter and Filter logic to be separate, and combining them reduces some duplication.) * Fix test. * improve JSON paste (#10256) * Set default server.maxsize to the sum of segment cache (#10255) * Default server.maxsize * Remove maxsize refs from config Co-authored-by: Atul Mohan <[email protected]> * Vectorization support for long, double, float min & max aggregators.

(#10245) 1) lookupId could return IDs beyond maxId if called with a recently added value. 2) getRow could return an ID for null beyond maxId, if null was recently encountered in a dimension that initially didn't appear at all. (In this case, the dictionary ID for null can be > 0). Also add a comment explaining how this stuff is supposed to work. * Clarify documentation on dimensions, dimensionExclusions.

Due to the way aggregators work across segments it's possible for the same query operating on the same data to produce slightly different results. The same problem exists with any aggregators that are not commutative since the merge order across segments is not guaranteed. * Also talk about doubles * Apply suggestions from code review * Don't log the entire task spec (#10278) * Don't log the entire task spec * fix lgtm * fix serde * address comments and add tests * fix tests * remove unnecessary codes * fix connectionId issue with JDBC prepared statement queries and router (#10272) * fix router jdbc prepared statement connectionId issue * column metadata too * style * remove tls * try tls again * add keystore stuffs * use keyManager password * add unit test * simplify * Fix CombiningFirehose compatibility (#10264) * Fix CombiningFirehose * Add integration test * Fix path * Add full datasource name * Fix input location Co-authored-by: Atul Mohan <[email protected]> * Segment backed broadcast join IndexedTable (#10224) * Segment backed broadcast join IndexedTable * fix comments * fix tests * sharing is caring * fix test * i hope this doesnt fix it * filter by schema to maybe fix test * changes * close join stuffs so it does not leak, allow table to directly make selector factory * oops * update comment * review stuffs * better check * Add maxNumFiles to splitHintSpec (#10243) * Add maxNumFiles to splitHintSpec * missing link * fix build failure; use maxNumFiles for integration tests * spelling * lower default * Update docs/ingestion/native-batch.md Co-authored-by: Abhishek Agarwal <[email protected]> * address comments; change default maxSplitSize * spelling * typos and doc * same change for segments splitHintSpec * fix build * fix build Co-authored-by: Abhishek Agarwal <[email protected]> * Add SQL "OFFSET" clause. (#10279) * Add SQL "OFFSET" clause. Under the hood, this uses the new offset features from #10233 (Scan) and #10235 (GroupBy). Since Timeseries and TopN queries do not currently have an offset feature, SQL planning will switch from one of those to Scan or GroupBy if users add an OFFSET. Includes a refactoring to harmonize offset and limit planning using an OffsetLimit wrapper class. This is useful because it ensures that the various places that need to deal with offset and limit collapsing all behave the same way, using its "andThen" method. * Fix test and add another test. * introduce interning of internal files names in SmooshedFileMapper (#10295) * Redis cache extension enhancement (#10240) * support redis cluster * add 'password', 'database' properties * test cases passed * update doc * some improvements * fix CI * add more test cases to improve branch coverage * fix dependency check for test * resolve review comments * Optimize large InDimFilters (#10312) * Optimize large InDimFilters For large InDimFilters, in default mode, the filter does a linear check of the set to see if it contains either an empty or null. If it does, the empties are converted to nulls by passing through the entire list again. Instead of this, in default mode, we attempt to remove an empty string from the values that are passed to the InDimFilter. If an empty string was removed, we add null to the set * code review * Revert "code review" This reverts commit 61fe33ebf762764bb89108ddd966937f3313be71. * code review - less brittle * ExpressionFilter: Use index for expressions of single multi-value columns. (#10320) Previously, this was disallowed, because expressions treated multi-values as nulls. But now, if there's a single multi-value column that can be mapped over, it's okay to use the index. Expression selectors already do this. * Clarify SQL behavior for multi-value dimensions. (#10276) There are some known inconsistencies between SQL and native that users should be aware of. * Remove NUMERIC_HASHING_THRESHOLD (#10313) * Make NUMERIC_HASHING_THRESHOLD configurable Change the default numeric hashing threshold to 1 and make it configurable. Benchmarks attached to this PR show that binary searches are not more faster than doing a set contains check. The attached flamegraph shows the amount of time a query spent in the binary search. Given the benchmarks, we can expect to see roughly a 2x speed up in this part of the query which works out to ~ a 10% faster query in this instance. * Remove NUMERIC_HASHING_THRESHOLD * Remove stale docs * refactor internal type system (#9638) * better type tracking: add typed postaggs, finalized types for agg factories * more javadoc * adjustments * transition to getTypeName to be used exclusively for complex types * remove unused fn * adjust * more better * rename getTypeName to getComplexTypeName * setup expression post agg for type inference existing * more javadocs * fixup * oops * more test * more test * more comments/javadoc * nulls * explicitly handle only numeric and complex aggregators for incremental index * checkstyle * more tests * adjust * more tests to showcase difference in behavior * timeseries longsum array * Handle internal kinesis sequence numbers when reporting lag (#10315) * Handle internal kinesis sequence numbers when reporting lag * add unit test * Adding supported compression formats for native batch ingestion (#10306) * Adding supported compression formats for native batch ingestion * Update docs/ingestion/native-batch.md Co-authored-by: sthetland <[email protected]> * fix spellcheck Co-authored-by: Suneet Saldanha <[email protected]> Co-authored-by: sthetland <[email protected]> * Add support for all partitioing schemes for auto compaction (#10307) * Add support for all partitioing schemes for auto compaction * annotate last compaction state for multi phase parallel indexing * fix build and tests * test * better home * Fix handling of 'join' on top of 'union' datasources. (#10318) * Fix handling of 'join' on top of 'union' datasources. The problem is that unions are typically rewritten into a series of individual queries on the underlying tables, but this isn't done when the union is wrapped in a join. The main changes are in UnionQueryRunner: 1) Replace an instanceof UnionQueryRunner check with DataSourceAnalysis. 2) Replace a "query.withDataSource" call with a new function, "Queries.withBaseDataSource". Together, these enable UnionQueryRunner to "see through" a join. * Tests. * Adjust heap sizes for integration tests. * Different approach, more tests. * Tweak. * Styling. * Move tools for indexing to TaskToolbox instead of injecting them in constructor (#10308) * Move tools for indexing to TaskToolbox instead of injecting them in constructor * oops, other changes * fix test * unnecessary new file * fix test * fix build * SQL support for union datasources. (#10324) * SQL support for union datasources. Exposed via the "UNION ALL" operator. This means that there are now two different implementations of UNION ALL: one at the top level of a query that works by concatenating subquery results, and one at the table level that works by creating a UnionDataSource. The SQL documentation is updated to discuss these two use cases and how they behave. Future work could unify these by building support for a native datasource that represents the union of multiple subqueries. (Today, UnionDataSource can only represent the union of tables, not subqueries.) * Fixes. * Error message for sanity check. * Additional test fixes. * Add some error messages. * Remove implied profanity from error messages.

Only the github `README.md` has been updated, not the `README.template` used for src and bin packages because presumably if you are reading from either of those you are just going to run locally and so the local quickstart is appropriate. * optimize announceHistoricalSegments (#9935) * optimize announceHistoricalSegment * optimize announceHistoricalSegment * revert offline SegmentTransactionalInsertAction uses a separate lock * optimize segmentExistsBatch: Avoid too many elements in the in condition * add unit test && Modified according to cr Co-authored-by: xiangqiao <[email protected]> * Fix VARIANCE aggregator comparator (#10340) * Fix VARIANCE aggregator comparator The comparator for the variance aggregator used to compare values using the count.

Unlike the `Datasource` input, the `Interval` input did not have a blue outline to indicate that it was required as the `IntervalInput` component did not support an `intent` property. * Compaction config UI optional numShards (#10446) * Compaction config UI optional numShards Specifying `numShards` for hashed partitions is no longer required after https://github.com/apache/druid/pull/10419.

(#10430) * RowBasedIndexedTable: Add specialized index types for long keys. Two new index types are added: 1) Use an int-array-based index in cases where the difference between the min and max values isn't too large, and keys are unique. 2) Use a Long2ObjectOpenHashMap (instead of the prior Java HashMap) in all other cases. In addition: 1) RowBasedIndexBuilder, a new class, is responsible for picking which index implementation to use. 2) The IndexedTable.Index interface is extended to support using unboxed primitives in the unique-long-keys case, and callers are updated to use the new functionality. Other key types continue to use indexes backed by Java HashMaps. * Fixup logic. * Add tests. * vectorize constant expressions with optimized selectors (#10440) * Web console: switch to switches instead of checkboxes (#10454) * switch to switches * add img alt * add relative * change icons * update snapshot * Fix the offset setting in GoogleStorage#get (#10449) * Fix the offset in get of GCP object * upgrade compute dependency * fix version * review comments * missed * Fix the task id creation in CompactionTask (#10445) * Fix the task id creation in CompactionTask * review comments * Ignore test for range partitioning and segment lock * Web console reindexing E2E test (#10453) Add an E2E test for the web console workflow of reindexing a Druid datasource to change the secondary partitioning type. The new test changes dynamic to single dim partitions since the autocompaction test already does dynamic to hashed partitions. Also, run the web console E2E tests in parallel to reduce CI time and change naming convention for test datasources to make it easier to map them to the corresponding test run. Main changes: 1) web-consolee2e-tests/reindexing.spec.ts - new E2E test 2) web-console/e2e-tests/component/load-data/data-connector/reindex.ts - new data loader connector for druid input source 3) web-console/e2e-tests/component/load-data/config/partition.ts - move partition spec definitions from compaction.ts - add new single dim partition spec definition * Fix UI datasources view edit action compaction (#10459) Restore the web console's ability to view a datasource's compaction configuration via the "action" menu. Refactoring done in https://github.com/apache/druid/pull/10438 introduced a regression that always caused the default compaction configuration to be shown via the "action" menu instead. Regression test is added in e2e-tests/auto-compaction.spec.ts. * Allow using jsonpath predicates with AvroFlattener (#10330) * Improve UI E2E test usability (#10466) - Update playwright to latest version - Provide environment variable to disable/enable headless mode - Allow running E2E tests against any druid cluster running on standard ports (tutorial-batch.spec.ts now uses an absolute instead of relative path for the input data) - Provide environment variable to change target web console port - Druid setup does not need to download zookeeper * Web console: fix lookup edit dialog version setting (#10461) * fix lookup edit dialog * update snapshots * clean up test * fix array types from escaping into wider query engine (#10460) * fix array types from escaping into wider query engine * oops * adjust * fix lgtm * Update version to 0.21.0-SNAPSHOT (#10450) * [maven-release-plugin] prepare release druid-0.21.0 * [maven-release-plugin] prepare for next development iteration * Update web-console versions * Test UI to trigger auto compaction (#10469) In the web console E2E tests, Use the new UI to trigger auto compaction instead of calling the REST API directly so that the UI is covered by tests. * adjustments to Kafka integration tests to allow running against Azure Event Hubs streams (#10463) * adjustments to kafka integration tests to allow running against azure event hubs in kafka mode * oops * make better * more better * vectorized group by support for nullable numeric columns (#10441) * vectorized group by support for numeric null columns * revert unintended change * adjust * review stuffs * Close aggregators in HashVectorGrouper.close() (#10452) * Close aggregators in HashVectorGrouper.close() * reuse grouper * Add missing dependency * Web console: Don't include realtime segments in size calculations.
