Available cache backends are: We’ve just been removing write and read requests from MySQL. Follow me also on regilero. In this article we’ll study how to push all these caches in better places. So it’s a replacement for Cache Router where you can reuse the cache parts of Drupal7 cache backends in a Drupal6 website.

But this is not always true, depends a lot on your Drupal cache usages I xrupal before cache engines can be faster in both write and read operations. You would get bigger numbers on a big website. Cache tables are small and not heavily used. But anyway, the real problem in term of performance here is not on the size of caches or the size of the indexes, but on the number of read and write queries running on theses tables. Follow me also on regilero.

You may wonder why it is smart to use something which is not the database to perform the caching storage? Follow me also on regilero. For now we’ll just have a look at the cache tables problems.
The default situation Take your Drupal Database and check what are the cache tables used, here I’ll use a quite dfupal default Drupal installation on Drupal6: The only thing we need know is a documentation on how to configure these. So by definition it’s quite hard to perform some fine tunning on the MySQL server if this table is not removed.

But this is still a good question. Let’s look at a complete configuration, for Drupal6 the cache backport module would require these lines: This is always almost provided in the module documentation but we will use the cache backport module documentation as druapl example.

Keep in mind that you should never make a server swap. And the answer is that a relational database provides more services, it can for example provide a better persitency, or manage better simultaneous writes, or allow handling relationship between objects. But you will need to allow some memory for these new backends, maybe some of the memory given previously to MySQl or Apache. Take your Drupal Database and check what are the cache tables used, here I’ll use a quite basic default Drupal installation on Drupal But this is not always true, depends a lot on your Drupal cache usages I said before cache engines can be faster in both write and read operations.
With core modules only, adding Panels, some views and some other modules and you could grow up to requests.

In case of full cache overflow the cache is completely wiped out, so do not use that for long persistency. And One of the good points of this module is that it provides a centralized documentation on several cache backends which is spread on the different modules for Drupal7.
They will love the APC cache backend. For all the others bins you could apply a different policy. Drupal use a lot of caches 7.26 different levels but all of them are by default stored in the database.
Sorti finle CMS Drupal 8 a basculé dans un nouveau cycle de versions tous les 6 mois.
Separate cache Backends with Drupal6 and Drupal7
And the « cache router » module applied some of the ideas we’ll study later on this article. We coudl also talk about the lock API in Drupal lock. Cache tables are small and not heavily used. Available cache backends are: The first question is « where should I put crupal separate cache bin or each cache table for short? You may want to keep some bins in the database, but you should test the memcached backend for most bins.
We’ve just been removing write and read requests from MySQL. To use the well known memcached daemon. To be honest statistics tracking can also make a lot of write requests, but this is yet another problem The Cache Backend management is not responsible of the session storage at least by default.
So now you may ask « why don’t we use Cache engines for everything? There is also a MongoDB module providing a dru;al cache backend beta2that I did not test yet, powered by Damien Tournoud.
The cache management has been rewritten, using cache router and memcached ideas and try to put the things one step further in the core. You could also try the filecache backend, with a modern linux kernel often used files will get mapped into memory buffers and you may get good results.
