IMPALA-3724: Support Kudu non-covering range partitions
This commit adds support for non-covering range partitions in Kudu
tables. The SPLIT ROWS clause is now deprecated and no longer supported.
The following new syntax provides more flexibility in creating range
partitions and it supports bounded and unbounded ranges as well as single value
partitions; multi-column range partitions are supported as well.
The new syntax is:
DISTRIBUTE BY RANGE (col_list)
(
PARTITION lower_1 <[=] VALUES <[=] upper_1,
PARTITION lower_2 <[=] VALUES <[=] upper_2,
....
PARTITION lower_n <[=] VALUES <[=] upper_n,
PARTITION VALUE = val_1,
....
PARTITION VALUE = val_n
)
Multi-column range partitions are specified as follows:
DISTRIBUTE BY RANGE (col1, col2,..., coln)
(
PARTITION VALUE = (col1_val, col2_val, ..., coln_val),
....
PARTITION VALUE = (col1_val, col2_val, ..., coln_val)
)
