Nitin Goyal created SPARK-5880:
----------------------------------
Summary: Change log level of batch pruning string in
InMemoryColumnarTableScan from Info to Debug
Key: SPARK-5880
URL: https://issues.apache.org/jira/browse/SPARK-5880
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 1.2.1, 1.3.0
Reporter: Nitin Goyal
Priority: Trivial
Fix For: 1.3.0
In InMemoryColumnarTableScan, we make string of the statistics of all the
columns and log them at INFO level whenever batch pruning happens. We get a
performance hit in case there are a large number of batches and good number of
columns and almost every batch gets pruned.
We can make the string to evaluate lazily and change log level to DEBUG
