The following page has been changed by jaytang: http://wiki.apache.org/pig/zebra New page: #format wiki #language en #pragma section-numbers off = Apache Pig-Zebra Wiki = Zebra is a storage layer that provides a high level data access abstraction and a tabular view of data in Hadoop, and could free Pig users from implementing their own data storage/retrieval code. It provites * columnar storage format for fast data projection * schema language to manage physical storage metadata * CPU/space-efficient data serialization In the future, it could also support predicate pushdown for further performance improvement. Initially, Zebra is released as a contrib project in Pig and can become a hadoop subproject later on.
