Row-level indexing in bitmap indexes ------------------------------------ Key: HIVE-2078 URL: https://issues.apache.org/jira/browse/HIVE-2078 Project: Hive Issue Type: Improvement Reporter: Marquis Wang Priority: Minor
Row-level indexing would greatly improve bitmap indexes. Without row-level indexing, bitmap indexes are useless without using multiple indexes and combining their bitmaps, since a block is likely to have all distinct values a column has, as there are millions of rows in one block. -- This message is automatically generated by JIRA.
