Describe your changes:

Fixes #19800
This pull request enhances the ingest_table_sample_data method in OMetaTableMixin to better handle non-JSON-serializable types, specifically IP address objects, before serialization. It also adds comprehensive unit tests to ensure correct conversion and serialization of various data types, including IP addresses and binary data.

Improvements to data serialization:

  • Updated the pre-serialization logic in ingest_table_sample_data to convert ipaddress.IPv4Address and ipaddress.IPv6Address objects to their string representation, ensuring compatibility with JSON serialization. [1] [2]

Testing enhancements:

  • Added a new unit test module test_table_mixin.py to cover the pre-serialization logic, including tests for IPv4/IPv6 address conversion, binary data encoding, plain types, and mixed-type rows. This ensures robust handling of edge cases and maintains data integrity during ingestion.

Now Ipv4 sample data gets ingested

Pull request overview

Fixes ClickHouse sample data ingestion failures when table sample rows include ipaddress.IPv4Address / ipaddress.IPv6Address objects by converting them to JSON-serializable strings before TableData.model_dump_json() is called.

Changes:

  • Added pre-serialization conversion for IPv4/IPv6 address objects in OMetaTableMixin.ingest_table_sample_data.
  • Added unit tests covering IPv4/IPv6 conversion, bytes/base64 encoding behavior, and mixed-type rows.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated no comments.

File Description
ingestion/src/metadata/ingestion/ometa/mixins/table_mixin.py Converts IPv4Address/IPv6Address values to str during sample-data preprocessing to prevent serialization errors.
ingestion/tests/unit/metadata/ingestion/ometa/test_table_mixin.py Adds unit coverage for the sample-data preprocessing behavior (IP address conversion + existing bytes handling).
