CGrates in distrubuted mode

[Eloy Coto Pereiro]

Hey,

Long time without touching CGRates. It works pretty well, so I don't have

issues, so well done and thanks! ;-)

Ok, we are growing quite fast and I have a new scenario. Nowadays we have a

CGRates in Master-Slave config, so if one breaks we launch the another one.

But now we built another datacenter, and we need to work in parallel with 2

CGrates instances, so here our example:

- DC1:

   2 Kamailio instances

   1 Cgrates instance in HA

- DC2:

    2 Kamailio instalces

    1 CGrates instance

So, CGRates services are going to use the same Redis+Postgres. But not sure if

any way to share the Tarrifplans, CDRstats and credits. Any hint if this is

possible? Any advice?

Another doubt is, nowadays I'm using the API to load all the data. Could CGRates

work in parallel?

Regards

Thanks also for feedback as always ;).

All TP configs will be shared by just using same db on both sites (and keeping cache in sync).
The only issue is with accounts since they are not cached and they need locking. For that you will still need master/slave unless you do partitioning since we don't exchange locks and it will slow the system quite considerably if we would distribute such.

On the other hand for your particular scenario would be useful the HA branch which we will integrate most probably in the next couple of weeks into master (already in testing phase).

work in parallel?

Yes for rating and all other subsystems than accounting. Accounting needs to stay in one rater always (or use balancer when one machine does not longer handle your rating traffic).

Hope this helps.
