Nick Dimiduk updated HBASE-24628:
---------------------------------
Release Note:
<!-- markdown -->
Introduces a new configuration,
`hbase.normalizer.throughput.max_bytes_per_sec`, for specifying a limit on the
throughput of actions executed by the normalizer. Note that while this
configuration value is in bytes, the minimum honored valued is `1,000,000`, or
`1m`. Supports values configured using the human-readable suffixes honored by
[`Configuration.getLongBytes`](https://hadoop.apache.org/docs/current/api/org/apache/hadoop/conf/Configuration.html#getLongBytes-java.lang.String-long-)

> Key: HBASE-24628
> URL: https://issues.apache.org/jira/browse/HBASE-24628
> Project: HBase
> Issue Type: Improvement
> Components: Normalizer
> Affects Versions: 3.0.0-alpha-1, 2.4.0
> Reporter: Nick Dimiduk
> Assignee: Nick Dimiduk
> Priority: Major
>
> There's no limits on the normalizer right now. It will iterate through the
> tables one at a time until it's touched all tables. For any table, it
> generates a complete plan and executes that plan in totality.
> It would be nice to allow operators to configure some limits here. Off the
> top of my head, the two metrics that might be interesting are {{split|merge
> actions / hour}} or {{hfile mb volume / hour}}. Either way, we'd need to
> track a little more metadata.
