Dalli Tests

Dalli is a high performance pure Ruby client for accessing memcached servers.

Dalli supports:

  • Simple and complex memcached configurations
  • Failover between memcached instances
  • Fine-grained control of data serialization and compression
  • Thread-safe operation (either through use of a connection pool, or by using the Dalli client in threadsafe mode)
  • SSL/TLS connections to memcached
  • SASL authentication

The name is a variant of Salvador Dali for his famous painting The Persistence of Memory.

Dalli would not exist in its current form without the contributions of many people. But special thanks go to several individuals and organizations:

  • Mike Perham - for originally authoring the Dalli project and serving as maintainer and primary contributor for many years
  • Eric Wong - for help using his kgio library.
  • Brian Mitchell - for his remix-stash project which was helpful when implementing and testing the binary protocol support.
  • CouchBase - for their sponsorship of the original development
