linghengqian opened a new pull request, #30146:
URL: https://github.com/apache/shardingsphere/pull/30146
Fixes #19517.
Changes proposed in this pull request:
- Bump Seata Client for testing to 2.0.0. This involves updating unit
tests.
- Document the problems with `org.antlr:antlr4-runtime:4.8` of Seata
Client. On the ShardingSphere side `4.10.1` is used.
- Documented issue with inability to operate the `undo_log` table. This
involves two aspects, one is the mismatch between Seata's Server and Client,
and the other is the lack of the `ext` field in the document's `undo_log` table.
