+	}


This will panic if nodeNum is greater than the number of . in the name. Instead, can probably do something like this (which ends up being more efficient too)

for _, series := range seriesList.Values { var ( name = series.Name() partsSeen int prefix string ) for i, c := range name { if c == '.' { partsSeen++ if partsSeen == nodeNum+1 { prefix = name[:i] break } } } if len(prefix) == 0 { continue } prefixMap[prefix] = struct{}{} }

I integrated this logic.

Better to use map[string]struct{} since it will not need to allocate

So for maps that only check membership, like you have here, you typically just use struct{} as the map type, to avoid allocating the additional byte; then just check for key existence, e.g. _, exists := prefixMap["check"], or range over only the keys, like you have here. This is a "go-ish" optimization Typically the actual savings aren't huge, but we still want to try and keep allocs down as much as possible

Ok, makes sense. I changed it to do it like this:

prefixMap := map[string]struct{}{}

+		prefix := strings.Join(strings.Split(series.Name(), ".")[:nodeNum+1], ".")


There may be an issue to using series.Name() here, since it's mutated when series are applied , e.g.

name := fmt.Sprintf("offsetToZero(%s)", series.Name()) series := ts.NewSeries(ctx, name, series.StartTime(), vals)

will change the name, so something like this may lead to using offsetToZero(foo.bar as the prefix; may need to add tracking for the original series name here? Unfortunately means it'll have to propagate everywhere we use NewSeries

ok it has been changed

This needs to be added within the lock since it's appending rather than inserting at an index. Probably better to lock the entire loop across values here

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 <ryanhall07@gmail.com> Date: Tue Sep 29 08:19:58 2020 -0700 Fix data race in TestSeekerManagerCacheShardIndices (#2679) commit c717d40 Author: Rob Skillington <rob.skillington@gmail.com> 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 <ryanhall07@gmail.com> 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 <ryanhall07@gmail.com> 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 <69990143+teddywahle@users.noreply.github.com> Date: Mon Sep 28 03:51:22 2020 -0700 [query] Implemented the Graphite `sortByMinima` function commit a7b499d Author: teddywahle <69990143+teddywahle@users.noreply.github.com> Date: Sun Sep 27 20:12:44 2020 -0700 [query] Implemented the Graphite `cumulative` function commit 13290be Author: Ryan Hall <ryanhall07@gmail.com> 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.
