Yifan Cai updated CASSANDRA-16967: ---------------------------------- Reviewers: Dinesh Joshi, Yifan Cai (was: Yifan Cai) > Probabilistic diff to sample partitions for diff testing based on probability. > ------------------------------------------------------------------------------ > > Key: CASSANDRA-16967 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16967 > Project: Cassandra > Issue Type: New Feature > Components: Tool/diff > Reporter: Jyothsna Konisa > Assignee: Jyothsna Konisa > Priority: Normal > > Probabilistic diff allows us to sample partitions randomly while running diff > tests. It takes new config parameter `partition_sampling_probability ` that > ranges between (0-1) and samples partitions based on this probability. The > default value for this config property is 1 which means that all the > partitions will be diffed. The partitions that are selected are also based on > the JobId, for a given sampling probability and JobId we always diff on same > partitions.This helps in reproducing any issues that one might run into. > Probabilistic diff allows us to run diff jobs on large clusters by sampling > some partitions. -- 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
