Hello Apache DataSketches PMC and Community,
This is a call for vote to release Apache DataSketches-cpp candidate
version 4.0.0-rc1
This is a major release with some API-breaking changes.
Changes since datasketches-cpp 3.5.1 release:
- Common sorted view used by all quantiles sketches with
simultaneous support for both inclusive and exclusive modes
- The default mode for all methods for querying quantiles sketches was
changed from exclusive to inclusive
- The mode is now a method parameter, not a template parameter
- Queries of empty quantiles sketches such as get_rank() and
get_quantile() will throw an exception now (returned NaN for floating point
types before)
- SerDe was removed from class templates and added to the relevant
method templates (such as serialize and deserialize)
- Support for comparator instances in quantiles sketches
- Support for equality operator instance in frequent items sketch
- Added operator-> to iterators over quantiles sketches
