Thank you all for joining today's meeting. Here are the notes I took: *Participants and what they would like to talk about:* Csaba (Cloudera): Scanners, Timestamps Quanlong (Hulu): *Want to know more about everyone’s focus area, whether Impala supports PB scale warehouse, can introduce the ORC scanner* Zoltan (Cloudera): Working on Parquet Daniel (Cloudera): Delta encoding Gabor (Cloudera): Working on upstream release, new patterns for timestamp conversion,* interested short discussion about release notes proposal* Attila (Cloudera): Working on date type support Laszlo (Cloudera): Infrastructure, toolchain Jeszy (Cloudera): Backline support Joe (Cloudera): Disk io manager, S3 guard Lars (Cloudera): Backend stuff
*Log of things we talked about* - Metadata issues: At 10s of PB, metadata becomes an issue (on 2.x). Discussed tips and tricks to improve refresh performance. - JDBC data source support, tracked in IMPALA-5741 <https://issues.apache.org/jira/browse/IMPALA-5741> - Release notes - Very long list, seems useful to have a shorter list - We shouldn't rely on release notes for compatibility, things just shouldn’t break. - Point out the highlights, focus more on advancements (Metadata, KRPC). - Gabor will send out a proposal for people to contribute. Thanks again for joining today. If you find these sessions *not helpful*, please reach out to me with a suggestion what we could improve. Otherwise I'll look forward to having another one in a few weeks.
