Hello,
As part of a large effort to reduce the negative impact of the DB queries in
the OpenSIPS performance, OpenSIPS 1.5.0 has now support for Memory Cache
(memcache). This is just a part of the effort of *optimizing the DB
interfacing* (part of this work is the upcoming *support for prepared
statements* in DB queries).
The Memory Caching support from OpenSIPS wants to provide a way of caching at
runtime different kind of data. These data will globally available (anywhere in
the routing script) and shared between all OpenSIPS processes.
The idea is to be able to store (cache) custom values for later usage. The main purpose of this MemCache support is to *reduce the number of DB queries by caching data* that does not need constant update from DB. DB queries are known to be one of bottle necks in the current design (see design considerations -
http://www.opensips.org/index.php?n=Development.NewDesign) and MemCache support will help in avoiding unnecessary DB hits.
To find out more about the design, implementation and usage examples for Memory
Caching, see *MemCache Tutorial* from the web site:
http://www.opensips.org/index.php?n=Resources.DocsTutMemcache
Best regards,
Bogdan
