> Hello,
>
> We tried out mini-batch mode and our Join suddenly had NoUniqueKey.
> Join:
> {code:java}
> Table membershipsTable = tableEnv.from(SOURCE_MEMBERSHIPS)
> .renameColumns($("id").as("membership_id"))
> .select($("*")).join(usersTable, $("user_id").isEqual($("id")));
> {code}
> Mini-batch config:
> {code:java}
> configuration.setString("table.exec.mini-batch.enabled", "true"); // enable
> mini-batch optimization
> configuration.setString("table.exec.mini-batch.allow-latency", "5 s"); // use
> 5 seconds to buffer input records
> configuration.setString("table.exec.mini-batch.size", "5000"); // the maximum
> number of records can be buffered by each aggregate operator task
> {code}
>
> Join with mini-batch:
> {code:java}
> Join(joinType=[InnerJoin], where=[(user_id = id0)], select=[id,
> group_id, user_id, uuid, owner, id0, deleted_at],
> leftInputSpec=[NoUniqueKey], rightInputSpec=[NoUniqueKey])
> {code}
> Join without mini-batch:
> {code:java}
> Join(joinType=[InnerJoin], where=[(user_id = id0)], select=[id, group_id,
> user_id, uuid, owner, id0, deleted_at], leftInputSpec=[HasUniqueKey],
> rightInputSpec=[JoinKeyContainsUniqueKey])
> {code}
