Rationale for this change
When reading Parquet files with large metadata (e.g., files with thousands of columns), the default Thrift message size limit can be insufficient, causing TTransportException: Message size exceeds limit errors. Currently, the Thrift protocol configuration uses default max message size (100MB), preventing users from reading files with exceptionally large metadata footers.
What changes are included in this PR?
Add a new configuration key: parquet.thrift.string.size.limit
Default value: 100 MB (104857600 bytes)
Allow users to override this via Configuration
Are these changes tested?
Yes and added a Test case TestParquetFileReaderMaxMessageSize.java
Are there any user-facing changes?
Not by default, user can set config parquet.thrift.string.size.limit= to increase it based on need.
Closes #GH-3358
