<p class="MsoNormal">The sql_cacher module doesn’t just read from SQL and store in local memory. It reads from SQL stores into a Cache-style (key-value) datastore. The Cache datastore doesn’t have to be in local memory; it can use any of the cache_db backends
supported by OpenSIPS. So you must configure the cache datastore that you want to use.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In your case, and I think most use cases for sql_cacher, you want to store in local memory, so you want to use the cachedb_local [1] module.<o:p></o:p></p>

</div>
<p class="MsoNormal">Hi.<o:p></o:p></p>
<p class="MsoNormal">I’m trying to set up an environment where I can fetch data from a local mysql database at startup and have it available for opensips in cached memory. So far I think the SQL_CACHER module can do this operation. But I’m getting a little
bit confused in the configuration. So far in the exported parameter “cache_table” I have:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">id <o:p>
</o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">db_url<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">cachedb_url<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">table<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">key<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">columns<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">on_demand<o:p></o:p></li></ul>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">In the DB_URL I have the SQL database where I store the date I want to fetch for later use.<o:p></o:p></p>
<p class="MsoNormal">But I’m confused with the CACHEDB_URL ? What’s the idea of this DB?. I’m getting the data from the DB_URL, but then I have to store it in this CACHEDB???... If so… can I use another table in the same SQL database?.. or I need to use another
method?. Can someone help me understand the whole picture here?.<o:p></o:p></p>
<p class="MsoNormal">In case I need to set up this “cachedb_url” what is recommended?... and how to set up?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
