TileDB v2.25.0 Release Notes

Announcements

  • TileDB 2.25, includes the new current domain feature which allows to specify an area of the domain that is considered to be active for sparse arrays.

  • Support for reading sparse fragments in dense arrays will be removed in version 2.27. Writing sparse fragments in dense arrays was removed in version 2.5. #5116
  • Support for returning the same results multiple times in sparse reads when ranges overlap will be removed in version 2.27. This was possible by setting sm.merge_overlapping_ranges_experimental to false, but the default true behavior has been there since version 2.17.
