Please Note The Board typically approves the minutes of the previous meeting at the beginning of every Board meeting; therefore, the list below does not normally contain details from the minutes of the most recent Board meeting.

WARNING: these pages may omit some original contents of the minutes.
This is due to changes in the layout of the source minutes over the years. Fixes are being worked on.

## Description:
Parquet is a standard and interoperable columnar file format
for efficient analytics. Parquet has 3 sub-projects:
- parquet-format: format reference doc along with thrift based metadata
definition (used by both sub-projects bellow)
- parquet-mr: java apis and implementation of the format along with
integrations to various projects (thrift, pig, protobuf, avro, ...)

## Issues:
there are no issues requiring board attention at this time

## Activity:
We have been working towards releasing parquet 1.11.0
We have been slow at validating the release.
This is dues in part to the scope of the release affecting the file
format itself and warranting more scrutiny to ensure backwards compatibility.
We are actively discussing how to improve our processes.
Current actions considered:
 - Clarify the vetting process for such releases.
 - Simplify/Automate the release validation process.
 - Review potential PMC candidates in our current contributors.
