  • Installing and Configuring Redis for Drupal 7, and other Memcached Alternatives | 2bits.com, Inc. - Drupal Performance Tuning and Optimization, Managed Hosting and Consulting
    Drupal Redis or Memcached modules and not have to write and test yet another caching module Non Memory Resident Storage We want to reduce the memory foot print of Redis Memcached because they both store the entire key value combinations in memory But still wanted to get acceptable performance The following products all claim to meet the above criteria but none of them worked for us They were tested on Ubuntu LTS 14 04 64 bit MongoDB Using MongoDB article for more details MemcacheDB MemcacheDB is a Memcached compatible server which used the excellent Berkeley DB database for storage This MemcacheDB presentation explains what it does in detail It has an Ubuntu package right in the repository so no need to compile from source or manually configure it It works flawlessly The N option enable the DB TXN NOSYNC option which means writes to the database are asynchronous providing a huge performance improvement Configuration in Drupal s settings php is very easy it is exactly like Memcached with only the port number changing from 11211 to 21201 Alas all is not rosy it is not really a cache layer since it does not expire keys values based on time like Memcached and Redis does Redis NDS Redis NDS is a fork of Redis 2 6 patched for NDS Naive Disk Store It does compile and run but when the line nds yes is added to the configuration file it is rejected as an invalid value Looking briefly in the source we also tried nds enabled yes but that was rejected as well So we could not get it to run in NDS mode ARDB ARDB is another NoSQL database that aims to be Redis protocol compatible We compiled this with three different storage engines The Facebook RocksDB did not compile to begin with Google s LevelDB compiled cleanly and so did WiredTiger But when trying to connect Drupal to it Drupal hanged and never came back with both engines SSDB SSDB is also another NoSQL database that tries to be Redis protocol compatible It compiled cleanly but had the same symptom as ARDB Drupal hangs and never receives back a reply from SSDB There are a couple of sandbox projects here and here that aim for native integration but no code has been committed so far in two years If you were able to get any of the above or another Redis Memcached compatible caching engine working please post a comment below Resources A useful article on Redis persistence Make sure you read this in conjunction with Redis own documentation on presistence Redis documentation on memory optimization The Pantheon Redis instructions are useful even though they are specific to their hosted service

performance reply Asynchronous Prefetch Database Query Cache Submitted by mikeytown2 not verified on Wed 2016 03 23 14 15 I ve found that the main issue when using MySQL as the cache backend has to do with the way queries are ran against it inside of Drupal and bad MySQL defaults I ve fixed every issue I ve come across when using MySQL as the cache backend As usual the status report page is helpful for configuration after installing this module https www drupal org project apdqc We ve had over 300 concurrent connections to MySQL from logged in users and didn t notice any slowdowns I m sure there are other use cases that I haven t thought of so any feedback would be appreciated reply Very good work Submitted by Khalid on Wed 2016 03 23 14 31 This is very good work Rather than it being just a cache layer I would love to see much of it within Drupal just like you did with the watchdog async writes That would benefit lots of areas in Drupal Caching can stay in memory caches like Memcached and Redis reply It started out as a bunch of Submitted by mikeytown2 not verified on Wed 2016 03 23 21 05 It started out as a bunch of core patches and I then rolled it into a module Drupal no longer hits a wall with the database once the site gets a good amount of traffic if using APDQC For the most demanding sites I totally agree that a memory cache is needed but I have yet to encounter a need for a non db cache while using APDQC Noted that I have plans to replace menu inc and path inc so I should see more gains in those areas once the queries have been designed for async and are MySQL
