Summary

pycrdt-store added support for compression and decompression callback functions in SQLiteYStore to compress Y updates and reduce database size (refer to y-crdt/pycrdt-store#8). This PR introduces traitlets in jupyter-collaboration to expose this compression functionality through configuration, allowing users to easily configure compression without code changes.

Changes

  • Added compress_function and decompress_function traitlets that accept dotted import paths
  • Automatic import and registration of compression callbacks when both functions are specified
  • Added test coverage for compression configuration

Usage

  • Via config file (e.g)
c.SQLiteYStore.compress_function = 'zlib.compress'
c.SQLiteYStore.decompress_function = 'zlib.decompress'
