Haohui Mai commented on FLINK-5829:
-----------------------------------
I just pushed a PR. The migration process is relatively straightforward except
that Calcite 1.12 seems to be conflicted with FLINK-4288.
The {{tableMap}} field has become a protected member thus unregister table
become non-trivial. There are two options here.
1. Revert FLINK-4288. FLINK-4288 has not been released yet thus it is okay to
pull it back with no concerns on backward compatibility.
2. Implement a proxy schema which inherits from {{CalciteSchema}} to regain the
access of the field.
[~fhueske] [~twalthr], what do you think?
> Bump Calcite version to 1.12 once available
