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.
