Laurent's question on SDB usage reminded me of another question i had for a while...
What is the pattern for handling obtaining/releasing the connection for each request that comes into FUSEKI in the case of DB backed stores ? From what we have seen, the same Dataset instance is used for each request and therefore if the connection is tied to the Dataset, there is a problem when there is concurrently running requests. What we have done with DB2 in case of Fuseki is that we create a dummy Dataset and in the - begin() method of the dummy Dataset, create the real dataset by giving it its own separate connection. It also ties the real dataset to the current threadID - all other methods first obtain the real dataset using the current threadID and delegate to the real dataset - end() method, releases the connection Mario
