Xiao Li updated SPARK-23202: ---------------------------- Target Version/s: 2.4.0 (was: 2.3.0) > Break down DataSourceV2Writer.commit into two phase > --------------------------------------------------- > > Key: SPARK-23202 > URL: https://issues.apache.org/jira/browse/SPARK-23202 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.3.0 > Reporter: Gengliang Wang > Priority: Major > > Currently, the api DataSourceV2Writer#commit(WriterCommitMessage[]) commits a > writing job with a list of commit messages. > It makes sense in some scenarios, e.g. MicroBatchExecution. > However, on receiving commit message, driver can start processing > messages(e.g. persist messages into files) before all the messages are > collected. > The proposal is to Break down DataSourceV2Writer.commit into two phase: > # add(WriterCommitMessage message): Handles a commit message produced by > \{@link DataWriter#commit()}. > # commit(): Commits the writing job. > This should make the API more flexible, and more reasonable for implementing > some datasources. -- 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
