Hi Nice to see you found this master thesis. It was indeed an analysis for improved concurrent update. The approach described in the thesis is too complex to implement in the current kernel. However, improving concurrent updates is high on our wish-list and we expect to improve it in one of the coming releases (in '17). regards, Martin Kersten On 24/11/2016 06:46, Puthick Hok wrote:

Hi,

I'm using MonetDB v11.23.13 (Jun2016-SP2). We decided to use MonetDB to store DNA marker data for our plant breeding platform (www.kddart.org http://www.kddart.org) 2 years ago based on MonetDB performance on data retrieval and data update is also good. The use of MonetDB is not purely OLAP. There are lot of aspects of OLTP because people need to load marker data from their genotyping services. We finish integrating MonetDB into the platform and developing more tools for the system. As the platform is getting more mature, we started to do concurrency testing against the system including the part that is relying on MonetDB.

Naively, I ran into a concurrency problem described in a master thesis by Rene Tassy (Improving Transactional Scalability in MonetDB). The work done in the thesis is very promising and I would like to thank you all for that. My question in relation to how I would deal with my problem is that what is the time frame for the improved MVCC Optimistic Concurrency Strategy in the MonetDB release?

Regards, Puthick
