   *  Filter specifying the boolean condition for the Artifacts to satisfy in
   *  order to be part of the Lineage Subgraph.
   *  The syntax to define filter query is based on https://google.aip.dev/160.
   *  The supported set of filters include the following:
   *  *  **Attribute filtering**:
   *     For example: `display_name = "test"`
   *     Supported fields include: `name`, `display_name`, `uri`, `state`,
   *     `schema_title`, `create_time`, and `update_time`.
   *     Time fields, such as `create_time` and `update_time`, require values
   *     specified in RFC-3339 format.
   *     For example: `create_time = "2020-11-19T11:30:00-04:00"`
   *  *  **Metadata field**:
   *     To filter on metadata fields use traversal operation as follows:
   *     `metadata.<field_name>.<type_value>`.
   *     For example: `metadata.field_1.number_value = 10.0`
   *  Each of the above supported filter types can be combined together using
   *  logical operators (`AND` & `OR`).
   *  For example: `display_name = "test" AND metadata.field1.bool_value = true`.
