Both execution modes impose significant c= onstraints on what that lifecycle must be, so the=C2=A0achievable consisten= t semantic is: * StreamWriter lasts for the duration of the query execution * DataWriterFactory lasts for the duration of the query execution * DataWriter (the task-level writer)=C2=A0has a lifecycle tied to each ind= ividual epoch This also allows us to restore the implicit semantic that DataWriter.commit= ()/abort() terminates the lifecycle. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
