Hernan Romer created HBASE-29976:
------------------------------------
Summary: Splitter is inefficient when splitting on single
characters
Key: HBASE-29976
URL: https://issues.apache.org/jira/browse/HBASE-29976
Project: HBase
Issue Type: Bug
Components: backup&restore
Reporter: Hernan Romer
Attachments: Screenshot 2026-03-06 at 1.27.35 PM.png
The BackupSystemTable uses a lot of Splitter#on(','), which automatically uses
a regex under the hood. Java String#split optimizes single character splits to
avoid uses regexes. At my company, we've seen that this can cause a lot of
HMaster churn, and lead to long running chores as a result.
We should replace these Splitter usages with String#split
