KAFKA-9039: Optimize ReplicaFetcher fetch path (#7443)
Improves the performance of the replica fetcher for high partition count fetch requests, where a majority of the partitions did not update between fetch requests. All benchmarks were run on an r5x.large. Vanilla Benchmark (partitionCount) Mode Cnt Score Error Units ReplicaFetcherThreadBenchmark.testFetcher 100 avgt 15 26491.825 ± 438.463 ns/op ReplicaFetcherThreadBenchmark.testFetcher 500 avgt 15 153941.952 ± 4337.073 ns/op ReplicaFetcherThreadBenchmark.testFetcher 1000 avgt 15 339868.602 ± 4201.462 ns/op ReplicaFetcherThreadBenchmark.testFetcher 5000 avgt 15 2588878.448 ± 22172.482 ns/op From 100 to 5000 partitions the latency increase is 2588878.448 / 26491.825 = 97. Avoid gettimeofdaycalls in steady state fetch states |

KAFKA-8841; Reduce overhead of ReplicaManager.updateFollowerFetchState (#7324)
This PR makes two changes to code in the ReplicaManager.updateFollowerFetchState path, which is in the hot path for follower fetches. Although calling ReplicaManager.updateFollowerFetch state is inexpensive on its own, it is called once for each partition every time a follower fetch occurs. 1. updateFollowerFetchState no longer calls maybeExpandIsr when the follower is already in the ISR. This avoid repeated expansion checks. 2. Partition.maybeIncrementLeaderHW is also in the hot path for ReplicaManager.updateFollowerFetchState. Partition.maybeIncrementLeaderHW calls Partition.remoteReplicas four times each iteration, and it performs a toSet conversion. maybeIncrementLeaderHW now avoids generating any intermediate collections when updating the HWM. **Benchmark results for Partition.updateFollowerFetchState on a r5.xlarge:** Old: ``` 1288.633 ±(99.9%) 1.170 ns/op [Average] (min, avg, max) = (1287.343, 1288.633, 1290.398), stdev = 1.037 CI (99.9%): [1287.463, 1289.802] (assumes normal distribution) ``` New (when follower fetch offset is updated): ``` 261.727 ±(99.9%) 0.122 ns/op [Average] (min, avg, max) = (261.565, 261.727, 261.937), stdev = 0.114 CI (99.9%): [261.605, 261.848] (assumes normal distribution) ``` New (when follower fetch offset is the same): ``` 68.484 ±(99.9%) 0.025 ns/op [Average] (min, avg, max) = (68.446, 68.484, 68.520), stdev = 0.023 CI (99.9%): [68.460, 68.509] (assumes normal distribution) ``` Reviewers: Ismael Juma <ismael@juma.me.uk>, Jason Gustafson <jason@confluent.io> |
