We may still fail to cache the > block if it is too big to fit any of the configured bucket sizes, or if we > fail to write it in the ioengine and reach the tolerated io errors threshold. > In such cases, the related block would remain in the > BucketCache.blocksByHFile indefinitely. -- This message was sent by Atlassian Jira (v8.20.10#820010)
