 * The `connectionSpecification` of the `ConnectorSpecification` must be valid JsonSchema. It describes what inputs are needed in order for the source to interact with the underlying data source.
   * e.g. If using a Postgres source, the `ConnectorSpecification` would specify that a `hostname`, `port`, and `password` are required in order for the connector to function.
   * The UI reads the JsonSchema in this field in order to render the input fields for a user to fill in.

   1. `config` - A configuration JSON object that has been validated using the `ConnectorSpecification`.
-  2. `catalog` - An `ConfiguredAirbyteCatalog`. This `catalog` should be constructed from the `catalog` returned by the `discover` command. To convert an `AirbyteStream` to a `ConfiguredAirbyteStream` copy the `AirbyteStream` into the stream field of the `ConfiguredAirbyteStream`. Any additional configurations can be specified in the `ConfiguredAirbyteStream`. More details on how this is configured in the [catalog documentation](catalog.md). This catalog will be used in the `read` command to both select what data is transferred and how it is replicated.

   3. `state` - A JSON object. This object is only ever written or read by the source, so it is a JSON blob with whatever information is necessary to keep track of how much of the data source has already been read. This is important whenever we need to replicate data with Incremental sync modes such as [Incremental Append](connections/incremental-append.md) or [Incremental Deduped History](connections/incremental-deduped-history.md). Note that this is not currently based on the state of data existing on the destination side.
 * Output:
   1. `message stream` - A stream of `AirbyteRecordMessage`s and `AirbyteStateMessage`s piped to stdout.

+This section will depict the lifecycle of a worker. It will only show the 2 connector version. The single connector version is the same with one side removed.
 
 Note: When a source has passed all of its messages, the docker process should automatically exit. After a destination has received all records, it should automatically shutdown. The worker gives each a grace period to shutdown on their own. If that grace period expires, then the worker will force shutdown.
