New Features

  • Introduce Rust driver token-based authentication We update the protocol version and introduce token-based authentication for all the available drivers. Now, instead of sending usernames and passwords for authentication purposes, authorization tokens are implicitly added to every network request to a TypeDB server. It enhances the authentication speed and security.

    These tokens are acquired as a result of driver instantiation and are renewed automatically. This feature does not require any user-side changes.

    Additionally, as a part of the HTTP client introduction work, we rename Concept Documents key style from snake_case to camelCase, which is a common convention for JSONs (it affects only value types: value_type -> valueType).

Bugs Fixed

Code Refactors

Other Improvements

  • Update dependencies After a recent update of the crates, rustls added aws-lc-rs as a default dependency. This caused runtime issues during loading of the shared library where the dynamic linker could not find some symbols from aws-lc:

    ImportError: dlopen(.../native_driver_python.so, 0x0002): symbol not found in flat namespace '_aws_lc_0_28_0_EVP_aead_aes_128_gcm'

    We decided to force the use of ring as the cryptographic provider for rustls instead.
