Aleksey Yeschenko commented on CASSANDRA-11324: ----------------------------------------------- You can initiate multiple scrub processes to run in parallel, processing one sstable each. It's not possible to parallelise scrub on a single sstable, however, as you really need to go byte by byte, without skipping. As such, closing as Not A Problem. > Make SSTABLESCRUB and related jobs multi-threaded / parallelize somehow > ------------------------------------------------------------------------ > > Key: CASSANDRA-11324 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11324 > Project: Cassandra > Issue Type: Improvement > Components: Tools > Reporter: Thom Valley > Priority: Minor > > SSTABLE scrub right now appears to be single threaded in offline mode (unsure > about online). When scrubbing a node, especially a well provisioned one, the > node sits mostly idle for potentially hours while scrubbing. > Making better use of available resources through parallelization / > multi-threading of the scrub process seems like a good idea. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
