Motivation

When using chain table, all the partition will chain and merge. But sometimes user's tables has non-datetime partition like :
PARTITIONED BY (region, date)
PARTITIONED BY (biz_type, dt)
PARTITIONED BY (country, city, date).
They want to keep the non-datetime partition separated and the datetime partition chain together.

Solution

target：separate partition to two type，control by config：chain-table.chain-partition-keys
Group Partition（prefix）：do not participate in chain, as group.
Chain Partition（suffix）：participate in chain，must be in the tail of partition.

Anything else?
