Alex Rodoni updated IMPALA-8405: -------------------------------- Issue Type: Bug (was: Improvement) > Document UDA state machine > -------------------------- > > Key: IMPALA-8405 > URL: https://issues.apache.org/jira/browse/IMPALA-8405 > Project: IMPALA > Issue Type: Bug > Components: Docs > Reporter: Tim Armstrong > Assignee: Alex Rodoni > Priority: Major > > The documentation in "The Underlying Functions for a UDA" doesn't do a good > job of explaining the state transitions that a UDA can go through. E.g. when > is Serialize() called. It's complicated because data needs to be serialized > to go over the network, but *sometimes* is serialized to spill to disk, which > changes the sequence of function calls. > See > https://community.cloudera.com/t5/Interactive-Short-cycle-SQL/Function-execution-flow-in-UDAs-and-memory-implications-for/m-p/88892#M5532?eid=1&aid=1 > for a user who is trying to understand this. -- 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
