SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Concord Database provides a deterministic, strongly consistent embedded KV store for Elixir using Raft, enabling reliable coordination across distributed nodes.

Core Features & Use Cases

  • Embedded CP KV store with Raft consensus for robust data replication
  • Rich API surface (put, get, delete, TTL, batch ops, queries, indexing, backups)
  • Suitable for building state machines, multi-node apps, and reliable configuration data in Elixir

Quick Start

Install Concord in your Elixir project and perform a put followed by a get to verify basic operations.

FAQPage Schema
How do I build a strongly consistent distributed KV store in Elixir?

A Raft consensus-based embedded KV store in Elixir provides deterministic apply semantics and robust data replication to ensure reliable coordination across multi-node deployments for strongly consistent state machines.

Can I use a Raft consensus KV store for state machine orchestration in Elixir?

Yes, a Raft consensus KV store is suitable for state machine orchestration in Elixir. It applies deterministic state transitions across multi-node deployments, ensuring reliable coordination and strongly consistent configuration data management.

What is the best way to handle distributed data replication in Elixir without external dependencies?

Using an embedded Raft-based KV store is an effective way to handle distributed data replication in Elixir without external database dependencies, ensuring strong consistency and deterministic apply semantics across nodes.

Does an embedded Raft KV store in Elixir support TTL, indexing, and backups?

Yes, an embedded Raft KV store in Elixir like Concord supports advanced data operations including TTL, indexing, and backups. It provides a rich API surface for put, get, delete, batch operations, and queries.

How do I start performing put and get operations with an embedded Elixir database?

To start performing put and get operations with an embedded Elixir database, install the Raft-based KV store in your Elixir project and execute a put followed by a get to verify basic operations.

When should I not use a strongly consistent embedded KV store for multi-node Elixir apps?

You should not use a strongly consistent embedded KV store if your multi-node Elixir app prioritizes high availability over consistency, as the Raft consensus protocol requires majority agreement, which can limit throughput during network partitions.
