JBoss Cache as a POJO Cache | |

I have a scenario in which huge data (in a database) needs to be updated from a xml. Before the data is updated, a lookup needs to be done against the d/b to decide which fields are to be updated / inserted. To do the lookup, I need to fire a query for each xml I get. This is very costly. Is it possible that the data from the d/b is pulled in a cache, and lookup happens against the cache? (i think this will save the trip to the database for lookup) Once the data is updated / inserted, the lookup cache needs to be refreshed to have the last updates. This needs to be done for each xml. Will jBoss-cache help with this? if yes, how? |

I'd say if the data size is huge, then it probably is not the best way to cache all the data. Probelm is memory and also query can take a while as well.
