While this works for a small scale > table snapshot, we found that for a table snapshot with many regions, the > locality calculation takes too much time. > In the case of a table with high locality, we can use region location from > meta table to decide a snapshot region's location. Add an option to support > it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
