• Fixed PyPI wheels load error on Windows due to building against TBB #419
• Fixed indexing of attribute named 'coords' #414
• open_dataframe now uses the underlying Array's nonempty_domain to avoid errors opening unlimited domain arrays #409

TileDB-Py 0.7.0

TileDB-Py 0.7.0 Release Notes

Wheels for this release are available on PyPI: https://pypi.org/project/tiledb/0.7.0/

TileDB Embedded updates:

• TileDB-Py 0.7.0 includes TileDB Embedded 2.1.2
  featuring a number of significant improvements, with major highlights including:
  • no longer uses Intel TBB for parallelization by default. Along with many benefits to TileDB Embedded, this
    significantly reduces complications and bugs with python multiprocessing fork mode.
  • Support coalescing subarray ranges to give major performance boosts.

Packaging Notes

• TileDB-Py 0.7 packages on PyPI support macOS 10.13+ and manylinux10-compatible Linux distributions only.
  For now, wheels could be produced supporting older systems but without Google Cloud Support; if needed,
  please contact us to discuss.

Improvements

• Added ".df[]" indexer tiledb.Array: directly returns a Pandas dataframe from a query (uses multi_index indexing behavior) #390
• Added parallel CSV ingestion example using Python multiprocessing with tiledb.from_csv #397
• Added wrapping and support for TileDB checksumming filters: ChecksumMD5Filter and ChecksumSHA256Filter #389
• Removed TBB install from default setup.py, corresponding to TileDB Embedded changes #389
• Add support for 'capacity' kwarg to from_csv/from_pandas #391
• Add support for 'tile' kwarg to from_csv/from_pandas to customize Dim tile extent #391
• Added '--release-symbols' option for building in release optimization with debug symbols #402
• Changed allows_duplicates default to True for from_csv/from_pandas #394

Bug fixes

• Fixed bug indexing anonymous attributes of sparse arrays using A[] (did not affect dense or multi_index) #404
• Fixed rendering of column name in mixed dtype exception #382
• Fixed forwarding of 'ctx' kwarg to from_csv/from_pandas #383
• Fixed type of return values for empty results when indexing a sparse array #384

Misc Updates

• Added round-trip tests for all filter repr objects #389

TileDB-Py 0.6.6

TileDB-Py 0.6.6 Release Notes

Note that we will be removing wheel support for macOS 10.9-10.12 in TileDB-Py 0.7 (planned for release in August 2020). This change is due to upstream (AWS SDK) minimum version requirements. The minimum supported version for macOS wheels on PyPI will be macOS 10.13.

Note that we will be removing support for manylinux1 wheels in TileDB-Py 0.7 (planned for release in August 2020). manylinux1 is based on CentOS5, which has been unsupported for several years. We now provide wheels built with manylinux2010, which is based on CentOS6 / glibc 2.12.

Improvements

• Bump release target to TileDB 2.0.8

Bug fixes

• Check for resizing offset buffers independently to fix query completion #377

TileDB-Py 0.6.5

TileDB-Py 0.6.5 Release Notes

We have added manylinux2010 wheels, corresponding to CentOS6 / glibc 2.12.

We are deprecating support for manylinux1 (CentOS5 / glibc 2.0.7), which is not supported by
the Google Cloud Storage SDK. We are planning to remove manylinux1 wheel support in the
TileDB-Py 0.7 release.

Improvements

• Enabled Google Cloud Storage support in macOS and linux (manylinux2010) wheels on PyPI (#364)

TileDB-Py 0.6.4

TileDB-Py 0.6.4 Release Notes

Improvements

• Bump release target to TileDB 2.0.6
• Improved error reporting for input data type mismatches #359
• Added tiledb.VFS.dir_size #343
• Added read and buffer conversion statistics for python to tiledb.stats_dump #354
• Implemented string deduplication to reduce conversion time for string arrays #357

Bug fixes

• Fixed argument order for Array.consolidate with a Config override parameter #344

TileDB-Py 0.6.3
