> There's been a few occasions where different customers had faced the need to reduce the number of regions for specific tables, either due to mistakenly pre-split or after a purge in table data. This jira is for adding a simple merge tool that takes the table name and the desired number of regions, then perform region merges until the total number of regions for the given table reached the passed valued.
