Michael Ho commented on IMPALA-8302: ------------------------------------ [~lv], please see IMPALA-6692. > Data stream senders should buffer limited amount of data when receivers block > ----------------------------------------------------------------------------- > > Key: IMPALA-8302 > URL: https://issues.apache.org/jira/browse/IMPALA-8302 > Project: IMPALA > Issue Type: Bug > Components: Backend, Distributed Exec > Affects Versions: Impala 3.2.0 > Reporter: Lars Volker > Priority: Major > > Exchanges into blocking nodes (e.g. sort nodes during run formation) can > block the whole execution if a single node blocks. Data stream senders should > buffer a limited amount of data to allow more sort nodes to start sorting > their data. Possible options would be a fixed amount of buffer size, or a > size relative to the sort node run size. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
