/check/table

URL: http://<db.host>:<db.port>/check/table

Scans the requested tables as specified in input parameter table_names for integrity. Any table chunks which fail the check will be marked as corrupt. By default the database will automatically repair corrupt tables (via truncating). Note that since this reads every table column from disk it may be a potentially long-running operation. The option local_only can be used to skip any table files already written to a remote storage. Returns table corruption results.
