> > @zhilinli123 I still don't understand the Jira ticket, so I can't really review it. Perhaps @snuyanzin or @eskabetxe understand the goal of this PR. > > For what I can assume, @zhilinli123 are trying to use scan.partition on a table that is hash partitioned by a string field.. > > My understanding of scan.partition is that only divides the query on multiples query based on params of scan.partition but is not using partitioning of table, it only adds "field BETWEEN ? AND ?" in query, and for that it only allow numeric, date, or timestamp column.. You're right, but slicing string hash md5 doesn't need to be done BETWEEN? AND ? It's much more efficient to check this shard directly -- This is an automated message from the Apache Git Service.
