[GitHub] [doris] AshinGau opened a new pull request, #15524: [fix](multi-catalog) get dictionary-encode from parquet metadata
AshinGau opened a new pull request, #15524:
URL: https://github.com/apache/doris/pull/15524
# Proposed changes
Issue Number: close #xxx
## Problem summary
Check whether a parquet is dictionary-encoded from file metadata instead of reading the first block. In some versions of parquet writer, the file format is not standard. We can't read the information from file metadata, but it's a dictionary-encoded column. In this case, the performance of reading delete files will be degraded.
