Perhaps name this "buffer-byte-added" to match the "byteDropped" naming?
Also can we add a byteConsumed when "IsDroppedOrConsumed" returns true and message is pruned from queue? That way we can tell bytes in -> matches bytes out <- whenever we debug.

added a buffer-byte-removed metric
Helpful for understanding how to size the buffer to survive a m3aggregator deploy. Due to the graceful shutdown of a m3agregator, it can take almost a minute between connections closing on the old instances and connections start taking traffic on the new instances. If a coordinator takes 10MB/s of traffic, it only takes 10s to fill up a 100MB buffer and start dropping requests.

There is no need to acquire the exclusive lock when flushing a connection. Instead the shared read lock can be acquired and individual connection exclusive locks can be acquired to ensure only a single writer is using the connection at a time. This is part of a broader fix to prevent deadlocks in the m3msg communication. Before this change and adding write timeouts, the producer and consumer could deadlock and stop all messages from flowing. If a producer was sending more messages than it was acking, it would eventually fill up the TCP buffers and begin to block writes. If the producer was flushing a connection and holding the exclusive lock, it would end up blocking with lock. Since the lock was held, the ACKing process could not clear the buffer and the flush would block forever. commit 192f611 Author: Ryan Hall <[email protected]> Date: Tue Sep 29 08:19:58 2020 -0700 Fix data race in TestSeekerManagerCacheShardIndices (#2679) commit c717d40 Author: Rob Skillington <[email protected]> Date: Mon Sep 28 23:27:09 2020 -0400 [documentation] Add documentation for disk read bytes per second limit (#2677) commit 3c81774 Author: Ryan Hall <[email protected]> Date: Mon Sep 28 11:25:08 2020 -0700 Add a configurable write timeout for consumer ACKs (#2675) Without a timeout this can potentially block forever. The producer and consumer can potentially dead lock trying to send/receive messages: Producer -> msg -> Consumer. Consumer is not attempting to read since it's trying to ACK. Consumer -> ack -> Producer. Producer is not attempting to read since it might be stuck trying to get a lock on the connection. For backwards compatibility this defaults to 0. We should set it to a sane default (5s) in the future. commit 80c9f9e Author: Ryan Hall <[email protected]> Date: Mon Sep 28 09:39:19 2020 -0700 Add queue processing metrics (#2671) * Add queue processing metrics I found these metrics useful when tracking down an issue with the queue processor. Additionally, added an optional consumer label for the message writer metrics so you can easily tell which downstream consumer is causing issues. Unfortunately, setting the consumer label is a little awkward since it only makes since for the replicated shard writer, which only has a single consumer instance at one time. For the shared shard writer, the empty string is used. commit 66b0b24 Author: teddywahle <[email protected]> Date: Mon Sep 28 03:51:22 2020 -0700 [query] Implemented the Graphite `sortByMinima` function commit a7b499d Author: teddywahle <[email protected]> Date: Sun Sep 27 20:12:44 2020 -0700 [query] Implemented the Graphite `cumulative` function commit 13290be Author: Ryan Hall <[email protected]> Date: Fri Sep 25 16:34:55 2020 -0700 Add metrics for bytes added/removed to the m3msg buffer (#2656) Helpful for understanding how to size the buffer to survive a m3aggregator deploy.

We are on a relatively old version, and gRPC frequently introduces breaking changes to APIs that are experimental. Our own query code, and the version of etcd we depend on, use experimental APIs which were later deprecated. We can't upgrade too far as we won't be able to import etcd. However v1.29 is far more compatible with other parts of the ecosystem, and makes it easier to integrate M3 in other environments (as well as integrate newer tools into M3). commit 5b95438 Author: Ryan Hall <[email protected]> Date: Fri Sep 25 13:53:08 2020 -0700 [msg] Move writer README to top level msg README (#2669) commit 38bc187 Author: Rob Skillington <[email protected]> Date: Fri Sep 25 14:12:05 2020 -0400 [query] Add metrics for remote storage backends (#2657) commit 21cceab Author: Rob Skillington <[email protected]> Date: Fri Sep 25 10:42:52 2020 -0400 [dbnode] Add example for using the Go DB node client to query/write metrics (#2658) commit 41b4bc4 Author: Rob Skillington <[email protected]> Date: Fri Sep 25 10:42:00 2020 -0400 [query] Add ability to enable optimized Graphite fanout if all agg namespaces have all the data (#2665) commit aefca00 Author: Linas Medžiūnas <[email protected]> Date: Fri Sep 25 09:09:46 2020 +0300 [dbnode] Large tiles aggregation flow v2 (#2643) * Refactor and cleanup * Refactor interfaces to more closely match design * Update frame iterator read from a encoding.ReaderIterator * Removing unnecessary files * az * Add utility to apply tile calculations on data. * test fix * Added concurrency * Concurrency logging * [dbnode] A noop AggregateTiles thrift RPC * Add AggregateTilesRequest.rangeType * sourceNameSpace / targetNameSpace * Drop AggregateTilesRequest.shardId * A partial implementation of AggregateTiles * Open DataFileSetReader and iterate through it * Decompress the data read * Add explicit FileSetType * [dbnode] Add OrderedByIndex option for DataFileSetReader.Open * Remove dbShard.TagsFromSeriesID * Regenerate mocks * Unit tests * Mockgen * Fix test * Resurrect rpc_mock.go * Remove accidentally committed files * Trigger build * Add step parameter * Write aggregated data to other namespace * Fix tests * Introduced AggregateTilesOptions * Minor improvements * Cleanup * PR response * Add headers * Remove unnecessary stuff. * [dbnode] A noop AggregateTiles thrift RPC * Add AggregateTilesRequest.rangeType * sourceNameSpace / targetNameSpace * Drop AggregateTilesRequest.shardId * A partial implementation of AggregateTiles * Open DataFileSetReader and iterate through it * Decompress the data read * Add explicit FileSetType * Remove dbShard.TagsFromSeriesID * Regenerate mocks * Unit tests * Mockgen * Fix test * Resurrect rpc_mock.go * Remove accidentally committed files * Trigger build * Add step parameter * Write aggregated data to other namespace * Fix tests * Introduced AggregateTilesOptions * Minor improvements * Cleanup * [dbnode] Integrate arrow iterators into tile aggregation * Fix close error after EOF * Can already close the SeriesBlockIterator * Update to use concurrent iteration and prefer single metadata * [dbnode] Cross block series reader * Assert on OrderedByIndex * Tests * Mocks * Dont test just the happy path * Compute and validate block time frames * [dbnode] Integration test for large tiles (#2478) * [dbnode] Create a virtual reverse index for a computed namespace * Return processedBlockCount from AggregateTiles * Improve error handling * Validate AggregateTilesOptions * Unnest read locks * Use default instead of constant * Fix test * minor refactoring * Addressed review feedback * Legal stuff * Refactor recorder * Allow using flat buffers rather than arrow * [dbnode] persist manager for large tiles * revert of .ci * minor * Adding better comparisons for arrow vs flat * Some fixes for query_data_files * An option to read from all shards * Fix large_tiles_test * Fix TestDatabaseAggregateTiles * Read data ordered by index * Generate mocks * Fix TestAggregateTiles * Group Read() results by id * Remodel CrossBlockReader as an Iterator * Mockgen * Erase slice contents before draining them * Resolve merge conflicts * Align with master * Integrate CrossBlockReader * Make a defensive copy of dataFileSetReaders * avoid panics * Improve TestNamespaceAggregateTiles * Added TODO on TestAggregateTiles * Align query_data_files * Mockgen * Added cross block iterator to be able to read multiple BlockRecords.
