Ximo Guanter updated SPARK-29248: --------------------------------- Target Version/s: (was: 3.0.0) > Pass in number of partitions to BuildWriter > ------------------------------------------- > > Key: SPARK-29248 > URL: https://issues.apache.org/jira/browse/SPARK-29248 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 3.0.0 > Reporter: Ximo Guanter > Priority: Major > > When implementing a ScanBuilder, we require the implementor to provide the > schema of the data and the number of partitions. > However, when someone is implementing WriteBuilder we only pass them the > schema, but not the number of partitions. This is an asymetrical developer > experience. Passing in the number of partitions on the WriteBuilder would > enable data sources to provision their write targets before starting to > write. For example, it could be used to provision a Kafka topic with a > specific number of partitions. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
