Normally, it will > fill the meta cache one region at a time by scanning the meta region. This > will cause huge pressure to the region server hosting meta during application > restart. > It can prefetching all region locations by calling > RegionLocator#getAllRegionLocations().Meta replica LoadBalance mode is > support in 2.4, it will be nice to load balance > RegionLocator#getAllRegionLocations() to all meta replica regions so batch > scan can spread across all meta replica regions. -- This message was sent by Atlassian Jira (v8.20.7#820007)
