Paul Yang commented on HIVE-1238:
---------------------------------
A couple of possibilities here:
1. Add 2 new functions to allow filtering of returned partitions with a
supplied partition spec. Disadvantage is that it will add to the growing number
of functions in the metastore API, and may result in redundant functionality.
{code}
// get_partition_mp methods allow filtering by matching a partial partition
// specification, as needed for dynamic partitions
list<Partition> get_partitions_mp(1:string db_name 2:string tbl_name
3:list<string> part_vals, 4:i16 max_parts=-1)
list<string> get_partitions_mp_by_name(1:string db_name,
2:string tbl_name, 3:list<string> part_vals, 4:i16 max_parts=-1)
{code}
2. Alter the signature of existing methods to allow specification of a partial
partition spec. An empty partition spec means 'return all'. Disadvantage is
that it may break existing apps once the new libraries are deployed.
{code}
// get_partition_mp methods allow filtering by matching a partial partition
// specification, as needed for dynamic partitions
list<Partition> get_partitions_mp(1:string db_name 2:string tbl_name
3:list<string> part_vals, 4:i16 max_parts=-1)
list<string> get_partitions_mp_by_name(1:string db_name,
2:string tbl_name, 3:list<string> part_vals, 4:i16 max_parts=-1)
{code}

> Key: HIVE-1238
> URL: https://issues.apache.org/jira/browse/HIVE-1238
> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Metastore
> Reporter: Paul Yang
> Assignee: Paul Yang
> Fix For: 0.6.0
>
>
> Currently, the metastore API only allows retrieval of all the partitions of a
> table, or the retrieval of a single partition given a complete partition
> specification. For HIVE-936, a method to retrieve all partitions that match a
> partial partition specification would be useful.
