TileDB v2.5.0 Release Notes

This release contains a major update to the sparse unordered with duplicates reader. In many cases this is a large performance increase for arrays and query layout that operate with this. The old reader is still available and can be toggled on with the config options highlighted below.

Configuration Changes

The config parameter for sm.use_refactored_readers has been split into three, sm.query.sparse_global_order.reader, sm.query.sparse_unordered_with_dups.reader and sm.query.dense.reader which take values of refactored or legacy. #2569

Breaking C API changes
