dylanhz updated FLINK-38852:
----------------------------
Release Note:
Bitmap is a new data type for storing sets of 32-bit unsigned integers with
adaptive compression, backed by RoaringBitmap. It is designed for scenarios
such as exact count distinct, multi-dimensional pre-aggregation analysis, and
retention analysis, where high-performance set algebra operations on large
integer sets are required.
Flink provides a rich set of built-in scalar and aggregate functions covering
bitmap construction, set operations (AND, OR, XOR, ANDNOT), cardinality
statistics, and format conversion directly in Flink SQL. The BITMAP type is
also available in the DataStream API via Types.BITMAP.
