> Key: HBASE-26190
> URL: https://issues.apache.org/jira/browse/HBASE-26190
> Project: HBase
> Issue Type: Bug
> Components: BucketCache, Operability
> Affects Versions: 2.4.5
> Reporter: Andrew Kyle Purtell
> Assignee: Kulwant Singh
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-2, 2.4.8

> These log lines may be printed at high frequency when using a schema that creates large blocks and the bucket cache is enabled. It makes sense to warn about this initially, but the very high rate of warnings when the use case is legit and this is expected does not. Print this once, then not again; or, rate-limit this message to be printed at a more reasonable rate, like once per minute.

> Also, it might be better to log this at INFO given the caveat "if size seems reasonable and you want it cached". Reads like an informational message.
