+ <description>
+ Allow JDO query pushdown for integral partition columns in metastore. Off
by default. This
+ improves metastore perf for integral columns, especially if there's a large
number of partitions.
+ However, it doesn't work correctly with integral values that are not
normalized (e.g. have
+ leading zeroes, like 0012). If metastore direct SQL is enabled and works,
this optimization
+ is also irrelevant.
