2024)¶

Added support for adding Decimal values.
Added support for binary arithmetic operations between floats and Decimals.
Added support for enabling and disabling theta sketches on specific columns by setting the table property bodo.write.theta_sketch_enabled.<column_name>.
Added support for new DDL commands:
- ALTER TABLE RENAME COLUMN
- ALTER TABLE ALTER COLUMN COMMENT
- ALTER TABLE ALTER COLUMN DROP NOT NULL
- DESCRIBE SCHEMA
- SHOW TBLPROPERTIES
- SHOW TABLES/VIEWS/SCHEMAS/OBJECTS without TERSE
(EXPERIMENTAL FEATURE) Added support for hints for indicating whether a join should be a broadcast join or for which side of a join should be the build side versus the probe side.
(EXPERIMENTAL FEATURE) Added support for increased caching based on covering expressions.

Expanded support for min/max I/O join filters to strings dates, floats, and timezone-naive timestamps.
Added limited datatype support for pushing low-cardinality join filters into I/O when the build side of a join has a small number of unique keys but where min/max filters are not very useful.
Added support for passing bitmasks in/out of runtime join filters to reduce the amount of redundant copying and improve performance when multiple join filters are applied in a row.
Optimized decimal scalar/array multiplication.
Added a sort based implementation for dense_rank.
Improved cost based decisions for filters and projections.

Fixed a bug occurring with join filters being pushed into Iceberg I/O on certain datatypes.
Fixed a bug so drop view / table if exists no longer throws exceptions when the table/schema does not exist.
