ZhaoYang created CASSANDRA-16044: ------------------------------------ Summary: Query SSTable Indexes in token sorted runs for LCS and TWCS Key: CASSANDRA-16044 URL: https://issues.apache.org/jira/browse/CASSANDRA-16044 Project: Cassandra Issue Type: Improvement Components: Feature/SASI Reporter: ZhaoYang
Currently SASI searches all SSTable indexes that may include the query partition key and indexed term, but this will cause large IO overhead with range index query (ie. age > 18) when sstable count is huge. Proposed improvement: query sstable indexes in token-sorted-runs lazily. When the data in the first few token ranges is sufficient for limit, SASI can reduce the overhead of searching sstable indexes for the remaining ranges. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
