> Currently JdbcStorageHandler does not split input in Tez. The reason is
> numSplit of JdbcInputFormat.getSplits can only pass via "mapreduce.job.maps"
> in Tez. And "mapreduce.job.maps" is not a valid param if authorizer(eg.
> SQLStdAuth) is in use. User ends up always use 1 split.
> We need to rely on this new feature if we want to support multi-splits. Here
> is my proposal:
> 1. Specify partitionColumn/numPartitions, and optional lowerBound/upperBound
> in tblproperties if user want to split jdbc data source. In case
> lowerBound/upperBound is not specified, JdbcStorageHandler will run max/min
> query to get this in planner. We can currently limit partitionColumn to only
> numeric/date/timestamp column for simplicity
> 2. If partitionColumn/numPartitions are not specified, don't split input
> 3. Splits are equal intervals without respect to data distribution
> 4. There is also a "hive.sql.query.split" flag vetos the split (can be set
> manually or automatically by calcite)
> 5. If partitionColumn is not defined, but numPartitions is defined, use
> original limit/offset logic (however, don't rely on numSplit).
