v.25.11New Feature
Add new virtual column _tags
Add new virtual column_tags(Map(String, String)) with all the tags associated with the blob in S3 (Note, if blob does not have any tags no extra request will be done). Resolves #72945. #77773 (Zicong Qu).
Why it matters
This feature provides users with easy and direct access to blob tags in S3 without requiring additional explicit requests or queries. It improves metadata visibility for objects in S3, enabling more efficient filtering, auditing, or management of blobs based on their tags. If the blob has no tags, no extra request is made, optimizing performance.How to use it
Users can simply include the virtual column_tags in their SELECT queries on tables using the S3 storage engine to retrieve associated blob tags. For example:SELECT _tags FROM <table_name> WHERE ...No additional configuration is needed; the column is available automatically.
