ML Metadata v1.2.0

Major Features and Improvements

• Open sources declarative nodes filtering with zetaSQL. It is currently
  supported on Linux and MacOS 10.14+.
• Extends get_artifacts, get_executions, get_contexts APIs with filtering
  capabilities on properties and 1-hop neighborhood nodes.
• Supports configure GRPC options grpc.http2.max_ping_strikes from the
  python client.

Bug Fixes and Other Changes

• Introduces database_name_ field for MySQL MetadataSource implementation to
  enable MySQLMetadataSource to switch to different databases within the same
  SQL server after connection or during reconnection.

ML Metadata v1.1.0

Major Features and Improvements

• Introduced skip_db_creation for MySQL backend. It is useful when db
  creation is handled by an admin process, while the lib users should not
  issue db creation clauses.
• Adds utils in shared C++ lib to delete Contexts, Artifacts, Executions, and
  their corresponding edges (e.g., Associations, Attributions,
  ParentContexts).
• Removes TensorFlow dependency in MLMD OSS C++ and TensorFlow bazel WORKSPACE
  dependency in MLMD OSS bazel WORKSPACE.
• Upgrades MLMD schema version to 7.
  • Add byte_value column for ArtifactProperty, ExecutionProperty,
    ContextProperty for better storing binary property values.
  • For MySQL backend, modify string_value to use MEDIUMTEXT instead of
    TEXT to persist property value upto 16MB.
  • Add index EventPath.idx_eventpath_event_id for Event retrieval
    queries.

Bug Fixes and Other Changes

• Depends on protobuf>=3.13,<4.
• Fixes a bug of increasing size of next_page_token over pagination calls.
• Returns InvalidArgumentError for PutParentContexts when creating a cyclic
