[jira] [Created] (ZOOKEEPER-4717) Cache serialize data in the request to avoid repeat serialize.
Yan Zhao created ZOOKEEPER-4717: --- Summary: Cache serialize data in the request to avoid repeat serialize. Key: ZOOKEEPER-4717 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4717 Project: ZooKeeper Issue Type: Improvement Components: server Affects Versions: 3.8.1 Reporter: Yan Zhao Fix For: 3.8.2 For each request, it will be serialized three times. 1. Leader proposal. It will serialize the request, wrap the serialized data in a proposal, then send the proposal to the quorum members. 2. SyncRequestProcessor append txn log. It will serialize the request, then write the serialized data to the txn log. 3. ZkDataBase addCommittedProposal. It will serialize the request, wrap the serialized data in a proposal, then add the proposal to committedLog. Serialization operations are CPU-sensitive, and when the CPU experiences jitter, the time required for serialization operations will also skyrocket. Therefore, we should avoid serializing the same request multiple times. -- This message was sent by Atlassian Jira (v8.20.10#820010)

+1 (binding) I did the following tests for the release candidate: - verified checksum and gpg signature of the artifacts - I built the source code (incl. the C-client, using -Pfull-build) on Ubuntu 18.04.2 using OpenJDK 8u372, maven 3.9.3 and GCC version 7.4.0 - all the unit tests passed (both Java and C-client) - I also built and executed unit tests for zkpython - I also built the java code (without -Pfull-build) using other JDK versions: 11.0.19, 17.0.7, 20.0.1 (but didn't run the tests this time, just used 'clean install -DskipTests') - checkstyle and spotbugs passed - apache-rat passed - owasp (CVE check) passed - fatjar built - I executed quick rolling-upgrade tests (using https://github.com/symat/zk-rolling-upgrade-test): - rolling upgrade from 3.5.10 to 3.8.2 - rolling upgrade from 3.6.4 to 3.8.2 - rolling upgrade from 3.7.1 to 3.8.2 - rolling upgrade from 3.8.1 to 3.8.1 - checked the generated documentation (zookeeper-docs/target/html) - compared generated release notes ( https://people.apache.org/~symat/zookeeper-3.8.2-rc0/website/releasenotes.html) with Jira ( https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310801=12352866 ) Best regards, Máté On Wed, Jul 5, 2023 at 11:20 PM Szalay-Bekő Máté wrote: > This is a bugfix release candidate for 3.8.2.

Hi Yan Zhao, I noticed you opened these 2 new tickets against the 3.9.0 fix version which is next release of ZooKepeer I'm just about to cut this week from the master branch. Do you think these tickets are blockers of 3.9.0? Regards, Andor
