sqlite support -------------- Key: ISPN-2980 URL: https://issues.jboss.org/browse/ISPN-2980 Project: Infinispan Issue Type: Feature Request Components: Loaders and Stores Affects Versions: 5.2.5.Final Reporter: Aleksandar Kostadinov Assignee: Mircea Markus Labels: cache-loader, cache-store, jdbc, sqlite It would be very nice is we have SQLite support for infinispan. SQLite is a powerful database supporting terabyte sized databases in a file with competitive performance. I tried to use it as a JDBC store but the best driver I find in the internet ([xerial sqlite jdbc driver|https://bitbucket.org/xerial/sqlite-jdbc]) does not implement full jdbc specification and trying to use it results in exceptions. I think that perhaps using the [non-jdbc wrapper sqlite4java|http://code.google.com/p/sqlite4java/] may make sense for infinispan because: 1. it promises better performance 2. it allows using the sqlite library from OS (xerial driver uses a customized build of sqlite) FYI here is how I setup sqlite for infinispan (unsuccessfully): {code}jboss as cli commands: /subsystem=datasources/jdbc-driver=sqlite:add(driver-name="sqlite",driver-module-name="org.xerial",driver-class-name=org.sqlite.JDBC) data-source add --name=SQLiteDS --connection-url="jdbc:sqlite:${sqlite.database.string}" --jndi-name=java:jboss/datasources/SQLiteDS --driver-name="sqlite" /subsystem=datasources/data-source=SQLiteDS:enable {code} {code}JBoss AS

driver [does not support|http://code.google.com/p/xerial/issues/detail?id=99] setBinaryStream(), only setBytes(). Not sure if there are any other methods required by infinispan but not implemented. As a simple comparison between JDBC and direct storage, I tried an app that caches 3000 records of around 5k and 60000 records of around 0.5k (total of less than 60MiB). Bdbje store operation completes in less than a minute. With a local mysql server it takes 10 minutes. And this is on a machine with plenty of CPU and memory over an SSD. Unfortunately bdbje does not work clustered for me (ISPN-2968). So my point is that a local disk based, fast, reliable, transactional engine is highly needed.
