redis-swapplex

Atomic state-transition based Redis multiplexing with reconnection notifications. Connection configuration is provided by env-url.

Why use this instead of redis::aio::ConnectionManager? - Error-free reconnection behavior: when a command would otherwise fail as a consequence of the connection being dropped, this library will immediately reconnect and retry when able without producing an otherwise avoidable IoError and with subsequent reconnections debounced 1500ms - Less contention overhead: the usage of arc_swap::cache::Cache results in a 10-25x speed up of cached connection acquisition. - ENV configuration makes life easier and simplifies kubernetes usage - Reconnects can be observed, thus allowing for Redis server-assisted client-side caching using client tracking redirection
