Ericsson/ered

Ered is an Erlang library that serves as a client for Valkey and Redis, supporting both standalone and cluster configurations. It provides core capabilities including asynchronous command execution, automatic pipelining, and RESP3 protocol support. The system manages connection supervision, cluster slot map convergence, and data parsing to ensure reliable communication with the database.

This entry introduces the ered library, an Erlang client designed to replace eredis and eredis\_cluster, supporting both standalone and cluster modes for Valkey and Redis (tested up to version 7.2). The release establishes the core API modules ered (for single-server connections) and ered\_cluster (for cluster operations), featuring automatic command pipelining, multiplexing over single connections, and support for RESP3. Key capabilities include asynchronous command execution, batch sending, routing commands to cluster replicas, and handling cluster slot map convergence. The project is currently in Beta with an unstable API.

The library has been renamed from 'redis' to 'ered' and restructured into a new module hierarchy. The standalone client API is now provided by the ered module (wrapping ered\_client), while cluster management is handled by ered\_cluster. The previous redis\_client and redis\_cluster2 modules have been removed and replaced by these new implementations, which include updated supervision trees (ered\_sup, ered\_client\_sup, ered\_cluster\_sup) and dedicated modules for command formatting (ered\_command) and information messages (ered\_info\_msg).

src · high confidence

Added a new, comprehensive test suite for the ered library, replacing the legacy redis\_client and redis\_connection tests. The suite includes ered\_client\_tests for basic client operations (connection, parsing, buffer management, authentication, and TLS), ered\_cluster\_SUITE for cluster functionality (commands, failover, pipeline, and replica support), and ered\_cluster\_convergence\_SUITE to verify cluster slot map consistency. Additionally, ered\_parser\_tests were updated to cover RESP3 features like NaN/Infinity floats, sets, and maps, ensuring the parser correctly handles these data types.
