Entry-point registration for a batch Src binding.

Registered via the tabsdatak.connectors entry point. Binds a Src config type to the SrcPlugin that reads it.

Parameters

parameter

type_str

Wire-stable identifier, unique across all plugins (sources, stream sources and destinations share one namespace), e.g. "s3-file-in". The registry's key.

parameter

systemstr

Human-readable name of the target system (e.g. "AWS S3"); shown by tdk connection types.

parameter

src_versionstr

Connector schema version.

parameter

connType[Conn]

Concrete Conn subclass the source binds to.

parameter

srcType[S]

Concrete Src subclass this binding registers.

parameter

table_modeTableMode

Whether read_in produces one file per slot or many; see TableMode.

parameter

cardinalityCallable[[S], int]

Callable returning the number of output slots src declares (e.g. lambda s: len(s.paths)).

parameter

pluginType[SrcPlugin]

SrcPlugin subclass implementing read_in.

parameter

explorerType[Explorer] | None

Optional Explorer for tooling introspection.

parameter

iconstr | None

Path to the connector's icon relative to the tabsdatak namespace root (e.g. "conn/s3/resources/s3.svg"), or None for none.
