Is there any difference between codeigniter's file cache and database cache?
I'm pertaining to these codes.
$this->cache->file->save()
vs
$this->db->cache_on();
Thanks!
db class caches queries, cache class caches output data

I would like to try implementing read-through = true and write-through = false cache. My application will read objects from cache and perform creates and updates directly to 3rd-party database (oracle).
How to tell Apache Ignite that I had updated object in Oracle?
You can remove an entry from the cache, using IgniteCache#remove, for example. It will be reloaded from the DB during next access.
I'm trying to cache database data to memcached. But I have a problem, I don't know how can I cache database data with activeDataProvider in yii2?
Anyone knows this?
For the purposes of dumping a Moodle db for backups, which tables can be exported as structure only (that is, they are cache tables safe to be truncated) ?
I don't want to export cached data as the backups are to be kept in a revision control system.
Thank you.
I would like to know if there's a way for ehcache to detect a database update/insert (spring/java, hibernate web application) and refresh its cache with the current(latest) data from the database if not, what would be the best way detect a database update so as to keep the data between and cache and database in sync?
Caching tools (ehcahce , infinispan) provides the solution other way round, i-e, to refresh the cache with DB data in configured interval , for example : every 15 or 30 minutes. Don't use cache, if the data keeps changing continuously...
I am having trouble clearing the Mondrian schema cache on my BI server. I go to
Tools->Refresh->Mondrian cache. But clear_mondrian_schema_cache.xaction does not seem to be clearing the cache.
I need the results to update as the source data changes, but I seem to keep getting cached results every time I issue a query.
Can someone help me with the API to enable periodic schema cache refresh?
i use the following bash script. which works nicely without any API faff :).
it is the equivalent of clicking tools > refresh > mondrian cache in the console.
the variable schema is the name of the schema which you see in the schema workbench app
#!bin/bash
#
# script to clean pentaho cache
user=XXX
pass=XXX
host=localhost
schema=Reporting%20schemas
wget --no-check-certificate http://${host}:2310/pentaho/content/analyzer/ajax/clearCache?catalog=${schema}\&userid=${user}\&password=${pass}
