> I don't remember if there is a registry for streaming writers There is. `StreamRDFWriter`. _opt-in behaviour_ Yes. It could be a new (custom) service delivered as a Fuseki module. Simplest case - a server that calls `constructTriples` and streams back N-triples or one of the Turtle formats that is streaming. This can be done as a split between a SELECT query stream returning the WHERE clause and a client side processing to apply the template. That gives the caller a way to control the potentially very large stream that "disappears" in the set semantics of CONSTRUCT. If they don't care about everything, just the streaming, `SELECT REDUCED` (or with LATERAL, limited per results). There are options here so a pushing all work to Fuseki may not that helpful. The stream could be chunks - or return results to the application in certain orders like same subject - via a combination of SELECT query and chunking results in the client side processing. -- This is an automated message from the Apache Git Service.
