Andrew Musselman commented on DRILL-3972: ----------------------------------------- Looks like WriterRecordBatch extends AbstractRecordBatch which implements CloseableRecordBatch in branch 1.2.0. First, do you recommend working in master? I was seeing some test failures at least so tried with a known-decent branch. Second, I'm a bit confused; would you suggest I write a new impl of CloseableRecordBatch, new extension of AbstractRecordBatch, or something else? > Vectorize Parquet Writer > ------------------------ > > Key: DRILL-3972 > URL: https://issues.apache.org/jira/browse/DRILL-3972 > Project: Apache Drill > Issue Type: Bug > Components: Storage - Parquet > Reporter: Julien Le Dem > Labels: pick-me-up > > Currently the > [ParquetRecordWriter|https://github.com/apache/drill/blob/a98da39dd5a8fa368afd8765f4e981826bbfcc0f/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/ParquetRecordWriter.java] > receives one record at a time and then turns that into columns. > Which means we convert from Drill columns to rows and then to Parquet columns. > Instead we could directly convert the Drill columns into Parquet columns in a > vectorized manner. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
