Fix filtering on boolean values in transformation #9812

jihoonson · 2020-05-03T00:25:07Z

Description

#9484 introduced a bug that a filter treats all boolean values as nulls in transformation. For example, the below transformSpec filters out all rows.

      "transformSpec": {
        "filter": {
          "type": "selector",
          "dimension": "booleanDimension",
          "value": "false"
        }

This PR fixes it by falling back to the previous behavior when rowValue has a complex type.

Another bug with strlen() on multi-valued columns is fixed in this PR as well. The strlen() function should allow only single-valued columns. On the query side, the caller should be able to automatically apply strlen() to each element in the multi-valued column, which is already implemented. On the ingestion side, however, it doesn't explode multi-valued column automatically, and strlen() on multi-valued columns should fail.

It's not obvious where dmFy comes from. What do you think about adding comment about base64 or adding a variable with a descriptive name?

Sounds good. Changed it to be more descriptive.

For anti-bug safety, it'd be good to have a Preconditions.checkState(stringValueValid) here.

This method is to check whether or not stringValue is initialized. It will explode this line.

Sorry, I meant to add this comment to getStringValue(). That's the one I was thinking should have the precondition check.

Ah good point. Added an assert. Also renamed getStringValue() and isStringValueValid() to getCachedStringValue() and isStringValueCached().

If I'm reading this right, eval really could be an array at runtime, so an assert isn't the right thing to do here. They are disabled by default outside of unit tests. So they're mostly useful for checking things that cannot possibly be false unless there is some bug in the software logic itself.

Besides that, since this error could happen due to legitimate user input, it should have a nicer error message.

Also, is there a reason to only adjust strlen in this patch? Lots of other functions have similar issues. I'm wondering if we should split this part off into a separate patch, and make sure we address it systematically.

Oh yeah, that's true. I forgot about that even though that was the original issue. I changed from throwing an exception to an assert here since it should never happen on the query side and apply() will be called per row. A systematic way to check before calling apply() makes most sense to me.

There is no reason to fix only strlen. I just happened to find it while adding unit tests and thought fixed it. I reverted this change back for now.

Removed this test for now. We can add it back when we fix #9824.

An attempt was made to fix this bug, however when running againts Guava's own tests, our version failed another half dozen tests, so it was decided to not continue down that path and scrap our own implementation. Explanation for how was this bug manifested itself: An exception thrown in BaseAppenderatorDriver.publishInBackground when invoked via transformAsync in StreamAppenderatorDriver.publish will cause the resulting future to never complete. This explains why when encountering https://github.com/apache/druid/issues/9845 the task will never complete, forever waiting for the publishFuture to register the handoff. As a result, the corresponding "Error while publishing segments ..." message only gets logged once the index task times out and is forcefully shutdown when the future is force-cancelled by the executor. * Document unsupported Join on multi-value column (#9948) * Document Unsupported Join on multi-value column * Document Unsupported Join on multi-value column * address comments * Add unit tests * address comments * add tests * Add REGEXP_LIKE, fix bugs in REGEXP_EXTRACT.

Because of this, they can not be converted to BigDecimal and instead throw a NumberFormatException. This change adds support for calculations that produce these numbers either for use in the `ROUND` function or the HavingSpecMetricComparator by not attempting to convert the number to a BigDecimal. The bug in ROUND was first introduced in #7224 where we added the ability to round to any decimal place.

Druid will only accept http requests with the method: GET, PUT, POST, DELETE and OPTIONS. If a Druid admin wants to allow other methods, they can do so by using the ServerConfig#allowedHttpMethods config. If a Druid user would like to disallow OPTIONS, this can be done by changing the AuthConfig#allowUnauthenticatedHttpOptions config * Exclude OPTIONS from always supported HTTP methods Add HEAD as an allowed method for web console e2e tests * fix docs * fix security IT * Actually fix the web console e2e tests * Ignore icode coverage for nitialization classes * code review * Move shardSpec tests to core (#10079) * Move shardSpec tests to core * checkstyle * inject object mapper for testing * unused import * Fix native batch range partition segment sizing (#10089) * Fix native batch range partition segment sizing Fixes #10057. 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.

Previously, pre-analyses were computed for multiple levels of the query, some of which were unnecessary. - Remove JoinFilterPreAnalysisGroup and join query level gathering code, since they existed to support precomputation of multiple pre-analyses. - Embed JoinFilterPreAnalysisKey into JoinFilterPreAnalysis and use it to sanity check at processing time that the correct pre-analysis was done. Tangentially related changes: - Remove prioritizeAndLaneQuery functionality from LocalQuerySegmentWalker. The computed priority and lanes were not being used. - Add "getBaseQuery" method to DataSourceAnalysis to support identification of the proper subquery for filter pre-analysis. * Fix compilation errors. * Adjust tests. * Filter on metrics doc (#10087) * add note about filter on metrics to filter docs * edit doc to include having and filtered aggregator links * Fix UnknownTypeComplexColumn#makeVectorObjectSelector * Fix RetryQueryRunner to actually do the job (#10082) * Fix RetryQueryRunner to actually do the job * more javadoc * fix test and checkstyle * don't combine for testing * address comments * fix unit tests * always initialize response context in cachingClusteredClient * fix subquery * address comments * fix test * query id for builders * make queryId optional in the builders and ClusterQueryResult * fix test * suppress tests and unused methods * exclude groupBy builder * fix jacoco exclusion * add tests for builders * address comments * don't truncate * Closing yielder from ParallelMergeCombiningSequence should trigger cancellation (#10117) * cancel parallel merge combine sequence on yielder close * finish incomplete comment * Update core/src/test/java/org/apache/druid/java/util/common/guava/ParallelMergeCombiningSequenceTest.java Fixes checkstyle Co-authored-by: Jihoon Son <[email protected]> * Revert "Fix UnknownTypeComplexColumn#makeVectorObjectSelector" (#10121) This reverts commit 7bb7489afc7a2cc496be93ae69681b6ab13a7c66. * update links datasketches.github.io to datasketches.apache.org (#10107) * update links datasketches.github.io to datasketches.apache.org * now with more apache * oops * oops * Fix Stack overflow with infinite loop in ReduceExpressionsRule of HepProgram (#10120) * Fix Stack overflow with SELECT ARRAY ['Hello', NULL] * address comments * fixes for ranger docs (#10109) * Fix UnknownComplexTypeColumn#makeVectorObjectSelector.
