Tim Armstrong created IMPALA-10405:
--------------------------------------
Summary: Consider setting parquet_page_row_count_limit to 20000 by
default
Key: IMPALA-10405
URL: https://issues.apache.org/jira/browse/IMPALA-10405
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
PARQUET-1414 did some experiments for parquet-mr that concluded that this
setting would enhance page filtering without giving up much compression. It's
the default over there.
We should probably just do the same in Impala because we already have that
evidence that it's better and we can avoid it being a confounding factor.
