AndySeaborne added a comment to T290240: Evaluate whether RDF Delta is a good idea to have in the backend.

Zookeeper keeps the index, the HA storage is usually in something with an S3 interface to use as a blob store.

@nguyenm9 - RDF Delta adds the replication of updates across a number of stores (Apache jena Fuseki).

@AWesterinen - Fuseki is part of Jena. Most of the subsystems have informal names. People refer to "Jena" or "Fuseki" interchangeably and the context is the task they are doing. Being more specific on naming didn't catch on.

All - I'm sorry that this sub-task is being redirected to be about Virtuoso. This would be better moved to the Virtuoso task.

AndySeaborne updated subscribers of T299460: Evaluate the Apache Jena Framework.

Hi @dcausse - TDB2 on it's own doesn't provide SPARQL nor any of the other features. TDB2 is just one low level storage choice - it's not a standalone thing and on its own can't provide any offloading from the central service. I hope you find the description clearer now.
