- Added YDB transport implementation (YDB_TRANSPORT_IMPL). Grpc transport implementation (GRPC_TRANSPORT_IMPL) is still used by default. New transport implementation doesnt have noticable advantages over grpc implementation yet. But it makes room for some further improvements.
- Removed internal proto files

- Extended logging for Session and SessionRetryContext
- Add URL Shortener demo application
- Reuse HashedWheelTimer in GrpcOperationTray
- Add JUnit tests with testcontainer support
- Add bulk upsert example
- Lowered logging level for some messages.
- Discovery host resolve check was softened. Now at least 1/2 resolved hosts of all that discovery returned is considered as a success resolve. This prevents from failing requests when some hosts can not be resolved.
- Added logging for locks in session pool.
- Added idempotent flag for SessionRetryContext which mark an operation as retryable.
- Added public method tryToConnect() for GrpcTransport allowing to add any logic in case of connection timeout or other errors.
- Added DiscoveryMode for GrpcTransport. SYNC mode is used by default, which means GRPCTransport will lock on constructor until grpc channel will be connected. This should improve session balancing on start with high load. It should also reduce latency of first requests.
- Fix String comparsion in CloudAuthHelper.
- Endpoint re-discovery now launches periodically as intended.
- All timers are now stopped on shutdown so the application should stop immediately.
- Added Random choice load balancer which is now used by default instead of round robin load balancer.
- Use a bit more modern GRPC name resolver factory API to facilitate GRPC implementation upgrades downstream.
- Added connection string support.
- Added CloudAuthProvider for cloud authentication with environment variables.
- Added AlterLogTable to ydb_logstore_v1.proto.
- Added fast backoff settings to SessionRetryContext. ABORTED and UNAVAILABLE status codes are retried with fast backoff now.
- Update junit from 4.12 to 4.13.1.
- Update protobuf from 3.6.1 to 4.15.6.
- Disabling client query cache does not disable server-side query cache anymore.
- Start initial changelog.
