QuakeWang opened a new pull request, #70: URL: https://github.com/apache/paimon-mosaic/pull/70
MosaicWriter builds `batch_col_map` from the initial Arrow schema, but `write_batch` previously only checked column count and non-nullable null counts. A later batch with the same number of same-typed columns but reordered field names could be accepted and written through the stale column map, silently storing values under the wrong column names. This patch validates each incoming batch against the writer schema before using `batch_col_map`: field name, logical type, and nullability must match. It also adds a regression test for the same-typed reordered-column case. -- This is an automated message from the Apache Git Service.
