Description

Currently there are quite a few places where we assume GZip as the compression codec which is incorrect, given that this is configurable and users might actually prefer to use different compression codec.

Examples:

Research direction
Search the Hudi codebase for hardcoded references to GZip as the default compression codec, particularly in HoodieParquetDataBlock and other related files. The issue indicates that multiple places assume GZip, while the compression codec is configurable. The goal is to identify all such occurrences and ensure that the configured codec is used consistently.
