Hi, All.
As of today, Apache ORC community recommends 1.8.0 as the latest version
and 1.7.6 as the stable version.
https://orc.apache.org/releases/
As announced in the mailing thread before,
https://lists.apache.org/thread/0prq5pt6wnm16zqnvthk85ljhxg7ycvs
The following projects were using 1.7.6.
- SPARK-40134 Update ORC to 1.7.6 (Apache Spark 3.4.0 3.3.1)
- ICEBERG #5580 ORC: Upgrade to 1.7.6 (Apache Iceberg 0.15)
- ARROW-17478 Update ORC to 1.7.6 (Apache Arrow 9.0)
- DRUID #12928 Update ORC to 1.7.6 (Apache Druid 0.24)
AFAIK, William actively made PRs to migrate them from 1.7.6 to 1.8.0.
Currently, the following is done and the others are under community reviews.
- Homebrew (orc-tools)
- Apache Spark 3.4.0 (SPARK-40323 Update ORC to 1.8.0)
Finally, note that Apache ORC 1.6.0 was released on 2019-09-03 (3 years
ago) and has served us well with 15 maintenance releases (1.6.11 ~ 1.6.14)
during its lifetime. Today, Apache ORC 1.6.0 reaches End-Of-Life and
branch-1.6 has no patch for 1.6.15.
https://github.com/apache/orc/commits/branch-1.6
The Apache ORC community is wondering if there is a blocker when 1.6.14
users migrate to 1.7.6 or 1.8.0. Please try 1.8.0/1.7.6 and let us
know within the next three days if there is a specific bug-fix backport
request and valid reasons. In that case, we may want to deliver an official
EOL release for that. Otherwise, we can skip 1.6.15 in favor of 1.7.6 and
1.8.0.
Cheers,
Dongjoon.
