WL#3682: Select proper TC from MySQL Server
Affects: Server-6.0 — Status: Code-Review — Priority: Low
In order to scale benchmarks and applications using more than 1 nodegroup it is essential that selection of TC is handled in an optimised manner from MySQL Server. The idea to handle this is that the first transaction if it accesses only one partition then the primary node of that partition will be selected for TC. This work will be performed most likely in NDB handler. This will make execution of DBT2 on very large scale possible and also many other benchmarks and applications. It's likely that this will cause a speed-up of a factor of 3-4 for large clusters when running DBT2. It is also essential to support the establishment of a new business area for MySQL Cluster for real-time applications such as financial applications for trading.
