Module compress

Traits

CompressionStrategy

Extendable compression interface, allowing implementations to explore different choices.

Functions

check_dtype_unchanged

Check that compression did not alter the dtype

check_statistics_unchanged

check_validity_unchanged

Check that compression did not alter the length of the validity array.

compute_precompression_stats

Eagerly compute certain statistics (i.e., pruning stats plus UncompressedSizeInBytes) for an array. This function is intended to be called in compressors, immediately before compression occurs.
