Bodo 2024.7 Release (Date: 7/9/2024)

New Features:

  • 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.

Performance Improvements:

  • 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.

Bug Fixes:

  • 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.
