OptionalbeforeThe query operation for communicating bindings.
The bus this actor subscribes to.
OptionalbusThe message that will be configured in the bus for reporting failures.

"RDF dereferencing failed: no actors could handle ${action.handle.mediaType}"
OptionalcacheThe cache size for COUNT queries.
If count queries should be sent to obtain the cardinality of (sub)queries. If set to false, resulting cardinalities will always be considered infinity.
If estimates for queries should be constructed locally from sub-query cardinalities. If set to false, count queries will used for cardinality estimation at all levels.
If URLs ending with '/sparql' should also be considered SPARQL endpoints.
Timeout in ms of how long count queries are allowed to take. If the timeout is reached, an infinity cardinality is returned.
OptionalforceForce an HTTP GET instead of default POST (when forceHttpGet is false) when the url length (including encoded query) is below this number.
If non-update queries should be sent via HTTP GET instead of POST
OptionalforceIf provided, forces the source type of a source.
