Summary of Changes

  • feat: add deterministic __hash__ methods to the all types
  • test: add tests to all new hash implementations
  • feat: add __eq__ method to TaggedTable and TimeSeries

The __hash__-Implementation is needed to more efficiently check whether data may be the same.
A deterministic implementation is used (based on xxhash, a fast non-cryptographic hash algorithm) to allow these comparisons to be performed across different interpreters (processes).

The implementation of the Schema was updated to be deterministic.
