Hi,
Apache IoTDB 0.12.2 RC2 is a bug-fix version from 0.12.1. It fixes 45 bugs
in v0.12.1, and brings a more stable compaction module.
You can get its main changes from [5].

Voting will be open for 72hr.
A minimum of 3 binding +1 votes and more binding +1 than binding -1
are required to pass.
Release tag: v0.12.2
Hash for the release tag: 9df86c5dbbcb4f36b0409dd00d99d892cdf2d0fc
Before voting +1, PMC members are required to download
the signed source code package, compile it as provided, and test
the resulting executable on their own platform, along with also
verifying that the package meets the requirements of the ASF policy
on releases. [3]
You can achieve the above by following [4].
[ ] +1 accept (indicate what you validated - e.g. performed the
