### What problem does this PR solve?
This commit adds a comprehensive suite of regression tests for the VARIANT
data type,
covering various scenarios including:
- Data Manipulation: Tests for INSERT, UPDATE, DELETE, and INSERT
INTO SELECT operations
on tables with VARIANT columns, including variations with
Merge-on-Write (MOW) tables
and concurrent operations.
- Predefined Schemas: Extensive tests for VARIANT columns with
predefined schemas,
covering all supported data types (including complex and nested
types), type casting,
and schema evolution (adding/dropping columns).
- Indexing:
- Verifies the functionality of inverted indexes on VARIANT
columns, including index
creation with field patterns (exact, wildcard, glob),
multi-index support, and
index usage in query filtering.
- Tests inverted index behavior with custom analyzers.
- Ensures correct query results when filtering on indexed VARIANT
sub-fields using
MATCH, =, IN, IS NULL, and array_contains.
- Compaction: Includes tests to ensure data correctness and schema
consistency after
cumulative and full compaction on tables with VARIANT columns,
especially with sparse
columns and predefined schemas.
- Functions: Adds tests for VARIANT-related functions like
variant_type and element
access functions.
- Edge Cases: Covers scenarios like loading from S3, handling of NULL
values, and bloom
filters on VARIANT columns.
Overall, this commit significantly strengthens the test coverage for the
VARIANT data
type, ensuring its stability and correctness across a wide range of use
cases.
