Phabricator updated HIVE-2600:
------------------------------
Attachment: HIVE-2600.D1005.1.patch
krishnakumar requested code review of "HIVE-2600 [jira] Enable/Add
type-specific compression for rcfile".
Reviewers: JIRA
adding schema-aware compression codec interfaces
Enable schema-aware compression codecs which can perform type-specific
compression on a per-column basis. I see this as in three-parts
1. Add interfaces for the rcfile to communicate column information to the
codec
2. Add an "uber compressor" which can perform column-specific compression on
a per-block basis. Initially, this can be config driven, but we can go for a
dynamic implementation later.
3. A bunch of type-specific compressors
This jira is for the first part of the effort.
