TypeDB Client Python 2.9.0

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.9.0

New Features

• Extend concept type API

We catch up client-nodejs with the Java client version 2.9.0, which exposes an extended set of APIs on Types.
We implement:

• ThingType.get_owns_explicit() and ThingType.get_owns_overridden
• AttributeType.get_owners_explicit()
• ThingType.get_plays_explicit()
• ThingType.get_plays_overridden()
• RelationType.get_relates_explicit() and RelationType.get_relates_overridden()

Bugs Fixed

Code Refactors

Other Improvements

• bump VERSION to 2.9.0

• Upgrade to Bazel 5

Make the repository use Bazel 5. Bazel 4 and below only work with the deprecated Python 2, which is no longer included in some operating systems such as the latest Mac OS X.

TypeDB Client Python 2.8.0

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.8.0

New Features

Bugs Fixed

Code Refactors

• Query iterator only throws exeption once

Revert previous changes from #247 and #248, which made query queues and iterators throw the same error idempotently. However, this goes counter to standard usage of iterators and queues, which are not meant to behave idempotently (each item is only returned once, and if they have an error they should no longer be used).

Other Improvements

• bump VERSION to 2.8.0

• Bazel Cache is disabled temporarily until SSL is fixed

• remove dead code

TypeDB Client Python 2.6.3

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.6.3

New Features

Bugs Fixed

• Don't delete response collectors in a transaction

We no longer delete response collectors in a transaction after receiving a response to a "single" request, or receiving a "DONE" message in a stream. This fixes a possible error when loading 50+ answers in one query and then performing a second query.

Code Refactors

Other Improvements

• Re-enable cluster tests

TypeDB Client Python 2.6.2

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.6.2

New Features

Bugs Fixed

• Move session pulse transmitter to the Client

Instead of launching a background thread in each session to send pulses, we now use a single thread in the Client to send pulses for all of its sessions. This allows the client to handle a much larger number of sessions than it previously could.

Code Refactors

• Store error on transaction stream

We store any exceptions received against the transaction stream (as well as query streams) in order to propagate the error to any future transaction operations, not just open query streams.

Other Improvements

• Update version to 2.6.2

• re-enable cluster tests

TypeDB Client Python 2.6.1

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.6.1

New Features

Bugs Fixed

Code Refactors

• Refactor behaviour utils

To match the other clients, we create a separate utils package for behaviour tests, rather than having a util file at the root of the behaviour tests.

Other Improvements

• Update @vaticle_dependencies and fix build

• disable cluster tests and update VERSION to 2.6.1

• Errors propagate through transaction

We align with Client NodeJS version 2.6.1 (mostly the work in typedb/typedb-driver-nodejs#197), which implements a better error propagation mechanism: when an exception occurs, we store it against all the transaction's active transmit queues to retrieve whenever the user tries to perform an operation in the transaction anywhere.

• reenable cluster tests

pip install typedb-client==2.6.0

New Features

• Implement and test transaction timeouts

We implement options for transaction timeout configuration (typedb/typedb#6487). We also add BDD implementation for new steps required to test transaction timeout and configuring transaction options.

Other Improvements

• bump VERSION

• Update build jobs to use Ubuntu 21.04

• Revert "Update build jobs to use Ubuntu 21.04"

• Update build jobs to use Ubuntu 21.04

• Update @vaticle_dependencies and the release notes creation script

TypeDB Client Python 2.5.0

PyPI package: https://pypi.org/project/typedb-client
Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.5.0

New Features

• Enable faster authentication with "user token" mechanism
  Authenticating a user by verifying their password introduces a significant overhead, which comes from the fact that the password is hashed with cryptographic hash function. In effect, opening a new session or transaction becomes much slower.
  We've now improved the speed of user-authentication by introducing a mechanism for verifying user credential with cheap "user token" rather than password.

Bugs Fixed

• Fix user authentication token not being sent to the server
  We've fixed two bugs regarding the user authentication token.

• Implement missing request builder implementation
  We've implemented the request builder for authentication token

• Implement missed token renewal step in Cluster client
  We have fixed the bug where some RPC methods in Cluster client does not perform token renewal step.

Code Refactors

• Remove connection factory classes
  We've renamed the terminology 'name' to 'username' since it's more appropriate.
  We've also simplified the architecture of both Core and ClusterServer clients by moving the channel and stub creation logic from the connection factory classes directly into the client classes.

Documentation: https://docs.vaticle.com/docs/client-api/python

Distribution

Available through https://pypi.org

pip install typedb-client==2.2.0

New Features

• Add concept cast methods, and add all Concept types to typedb.client
  We added methods to cast concept types to each other: for example concept.as_attribute() will now cast a Concept to an Attribute, throwing an exception if it is not actually an Attribute. This aids type checking systems.
  Also, all the Concept types are now importable from typedb.client directly.

• Implement cluster authentication
  Implemented authentication secure channels, and user management for typedb cluster.
  SSL is now required for connections to TypeDB cluster , because sending username/passwords over plaintext connections is disallowed by gRPC.
