Change subject: KUDU-613: Scan Resistant Caching ......................................................................

Just played around with some cache performance testing using the same workloads from cache-bench right now. The SLRU cache is significantly slower (4-6x) than the LRU cache. Looks like the locking will have to be on a shard level. I'll look into how to do that this weekend, any pointers/tips would be appreciated. -- To view, visit http://gerrit.cloudera.org:8080/20607 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I45531534a2049dd38c002f4dc7982df9fd46e0bb Gerrit-Change-Number: 20607 Gerrit-PatchSet: 5 Gerrit-Owner: Mahesh Reddy <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Mahesh Reddy <[email protected]> Gerrit-Reviewer: Tidy Bot (241) Gerrit-Comment-Date: Fri, 10 Nov 2023 07:31:33 +0000 Gerrit-HasComments: No
