There will be a lot of locating requests, but most of will have same results. Things become worse if we do batch operations with AsyncTable as we will send a locating request for each operation concurrently. > We need to reduce the redundant requests to meta table. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
