Hi Andy, Thank you for your reply, Andy. In my project, the scale of the data which is existed is about TB-level, and will extend to PB-level. And data sources will be distributed. According to what I read from document, TDB is based on memory and file database and on a single machine. So, I need SAP HANA for my data management and for distributed data store.
I checked link you referred, and what I concern is whether latest Jena (future version) will support SDB. If not, data migration will occur big trouble. If there is any better solutions please tell me. Thank you!

What scale of data stored in HANA sol you want to work with?
