TileDB 2.26.0-rc2

TileDB v2.26.0 Release Notes

Breaking behavior

• The superbuild architecture of the build system has been removed and TileDB is now a single-level CMake project. Build commands of the form make && make -C tiledb <targets> will have to be replaced by make <targets>. #5021

Breaking C API changes

• All deprecated C and C++ APIs were removed. #5146

New features

• Add support for getting the datatype of a ndrectangle dimension. #5229
• Add dim num support for ndrectangle. #5230

Improvements

• Added new functions to write schema dump to a string rather than stdout, so that non-console interactive environments such as Jupyter will be able to capture and print the output. #5026
• Improve dense read performance for small reads. #5145
• Skip caching redirect uri on array create. #5224
• Enable curl error retries. #5275

Deprecations

• Warn users using dense arrays with sparse fragments. #5116

Defects removed

• Fix fragment consolidation to allow using absolute URIs. #5135
• Reset offsets in buffer list for retries. #5220
• Fix symbol clashes between tiledb and pyarrow by building the AWS SDK with its internal symbols hidden. #5223

Configuration changes

• The sm.use_refactored_readers config option is no longer recognized. Refactored readers are used by default. To use the legacy reader, set the sm.query_(dense|sparse_global_order|sparse_unordered_with_dups)_reader config option (depending on the reader you are using) to legacy. #5183

API changes

C API

• Add ctx to CurrentDomain CAPI. #5219
• Add new CAPIs to dump array schema, attribute, dimension, domain, enumeration and group to a string. #5026
• Add serialization and API changes for post_array_schema_from_rest. #5261
• Add tiledb_array_schema_load_with_config C API to load the schema of an array with configuration. #5261

Build System Changes
