Dear Piotr,
Thank you for reply.
Does TDB itself has high availability function?
Yes. Same RDF Delta. https://afs.github.io/rdf-delta/
TDB is a database engine so HA means having at least copies on two
different machines.
Delta adds a shared transaction log to a cluster of TDB instances. They
could be embedded in an HA application. One such use is in Fuseki.
Fuseki+TDB is a database server. Fuseki provides the network connection
and protocol handling.
RDF Delta provides an RDF Dataset (over any base storage like TDB, 1 or
2), the HA protocol and distributed log backend.
