Mserver5 requires exclusive access to the database. There is no way around that. So you can have multiple mservers on a server, each serving another database, but you cannot have multiple mservers serving a single database, even with read only access. There would not be any benefit to that anyway as a single mserver5 will already use all available memory and all available cores to do its work. Two will only get in each others way. Hope this makes sense. Joeri On Wed, Oct 18, 2017 at 04:13:51AM +0000, Sharma, Sreejith wrote:
Thanks a ton, Joeri.
One last question - Can we run two instance of MonetDB in the same server? It's not about different database, but 2 instance of mserver.

Ah, you want MERGE TABLEs, in combination with REMOTE TABLEs.
You can build a merge table out of remote tables :)
There have been some bugs recently so be sure to use the most recent version of MonetDB.

Hi Joeri,
If we need to load balance, we can have the same tables sitting over 2 tablesspaces or 2 servers. This can help balance the load coming into same server and can share the load within servers.

Hi Sharma!
I’m not entirely sure what you mean with same table from 2 sources, could you give a more detailed example?
