Genmao Yu created SPARK-27355: --------------------------------- Summary: make query execution more sensitive to epoch message late or lost Key: SPARK-27355 URL: https://issues.apache.org/jira/browse/SPARK-27355 Project: Spark Issue Type: Improvement Components: Structured Streaming Affects Versions: 3.0.0 Reporter: Genmao Yu
In SPARK-23503, we enforce sequencing of committed epochs for Continuous Execution. In case a message for epoch n is lost and epoch (n + 1) is ready for commit before epoch n is, epoch (n + 1) will wait for epoch n to be committed first. With extreme condition, we will wait for `epochBacklogQueueSize` (10000 in default) epochs and then failed. There is no need to wait for such a long time before query fail, and we can make the condition more sensitive. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
