officialasishkumar opened a new pull request, #10943:
URL: https://github.com/apache/seatunnel/pull/10943
### Purpose of this pull request
Fixes #10928.
This PR normalizes Parquet field names consistently when writing INT96
values. The Parquet schema uses normalized lower-case field names, but the
INT96 timestamp/fixed lookup could still use the original SeaTunnel field name.
Mixed-case fields such as `createTime` could therefore miss the schema field
during write. The configured INT96 field list and automatically selected
timestamp fields now use the same normalization as schema and record writes.
### Does this PR introduce _any_ user-facing change?
Yes. Parquet sinks can now write INT96 timestamp/fixed fields whose
SeaTunnel column names contain uppercase letters without requiring lower-case
aliases.
