Phase 3 Research: Write Through Cache

We need to better understand how gridgain Write Through Cache could work

• what are the sql differences that could have larger architecture implications. The cost of missing wrong / caching wrong values.
• better understanding what gridgain cant do and how that impacts write through
• what is configured in gridgain to write through to mariadb
• how would gridgain handle failover of a primary (mariadb server) write through
• what is needed from maxscale to use gridgain for write through
• client -> maxscale -> gridgain -> server vs
• client -> gridgain -> maxscale -> server
• determine which connector to use between maxscale -> gridgain
• how gridgain handles mariadb protocol and what should we do about it
