qail-redis

⚠️ ALPHA - Early development. API may change.

"Redis stores time — QAIL decides."

Native Redis driver using the unified QAIL AST. Part of the QAIL decision layer: PostgreSQL (facts) + Qdrant (meaning) + Redis (time).

Installation

[dependencies]
qail-redis = "0.14"

Quick Start

use qail_redis::{RedisDriver, RedisExt};
use qail_core::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut driver = RedisDriver::connect("127.0.0.1", 6379).await?;
    
    // Unified Qail AST - same pattern as PostgreSQL/Qdrant
    driver.execute(&Qail::redis_set("session:123", b"data".to_vec()).redis_ex(3600)).await?;
    
    let value = driver.get_str("session:123").await?;
    println!("Session: {:?}", value);
    
    Ok(())
}

The QAIL Decision Layer

qail-redis is designed to work alongside qail-pg and qail-qdrant for unified data access:

use qail_core::prelude::*;
use qail_pg::PgDriver;
use qail_qdrant::QdrantDriver;
use qail_redis::{RedisDriver, RedisExt};

// Connect to all three backends
let pg = PgDriver::connect("postgres://localhost/app").await?;
let qdrant = QdrantDriver::connect("http://localhost:6334").await?;
let mut redis = RedisDriver::connect("127.0.0.1", 6379).await?;

// PostgreSQL: Facts (persistent relational data)
let users = pg.query(&Qail::get("users").filter("active", Eq, true)).await?;

// Qdrant: Meaning (semantic similarity)
let similar = qdrant.search(&Qail::search("products").vector(&embedding).limit(10)).await?;

// Redis: Time (ephemeral state, caching, sessions)
redis.execute(&Qail::redis_set("cache:user:123", user_json).redis_ex(300)).await?;
let cached = redis.get_str("cache:user:123").await?;

Same Qail type. Same philosophy. Different backends.

Available Commands

Connection Pooling

use qail_redis::{RedisPool, PoolConfig};

let pool = RedisPool::new(
    PoolConfig::new("127.0.0.1", 6379).max_connections(10)
);

let mut conn = pool.get().await?;
conn.set("key", b"value").await?;
// Connection returns to pool on drop

Features

• Unified Qail AST: Same Qail type as PostgreSQL and Qdrant
• Native RESP3: Direct wire protocol encoding (no string parsing)
• Connection Pooling: RedisPool with semaphore concurrency
• Fluent API: RedisExt trait for .redis_ex(), .redis_nx(), etc.
• Async/Await: Built on Tokio
