C. Scott Andreas updated CASSANDRA-8923: ---------------------------------------- Component/s: Local Write-Read Paths > Improve MergeIterator performance for binary prefix comparable data > ------------------------------------------------------------------- > > Key: CASSANDRA-8923 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8923 > Project: Cassandra > Issue Type: Improvement > Components: Local Write-Read Paths > Reporter: Benedict > Priority: Minor > Labels: compaction, performance > > Along the same lines as CASSANDRA-8915, only designed to help merges of small > partitions, or those with clustering prefixes that are binary prefix (or byte > order) comparable. The approach in CASSANDRA-8915 will work well for normal > intra-partition merges, but partition keys themselves are typically > distributed by hash, meaning there will very rarely be runs of keys owned by > a single source. A binary trie based merge would perform significantly better > here, and could also be rolled out alongside CASSANDRA-8731 for binary prefix > comparable fields. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
