OptunaSharp.Storage.StackExchange.Redis

Redis journal-log backend for OptunaSharp on StackExchange.Redis — the de-facto-standard .NET Redis client (MIT). Part of the SciSharp STACK.

StackExchangeJournalRedisBackend persists an Optuna study's operation log to a Redis server (standalone or cluster). It is byte-compatible with Python Optuna's optuna.storages.journal.JournalRedisBackend and with the sibling NRedisStack/ServiceStack backends — a study written by any of them can be read by the others over the same Redis.

Usage

using OptunaSharp.Storages;
using OptunaSharp.Storages.Journal;

var backend = new StackExchangeJournalRedisBackend("redis://localhost:6379");
var study = Optuna.CreateStudy(storage: new JournalStorage(backend));
study.Optimize(t => { var x = t.SuggestFloat("x", -10, 10); return (x - 2) * (x - 2); }, nTrials: 20);

redis://, rediss:// (TLS) and unix:// URLs are accepted (optional [user]:[pass]@, /db, ?db=). For a cluster, pass useCluster: true.

Native StackExchange.Redis configuration

The URL constructor mirrors Python Optuna, but you are not limited to it — drive StackExchange.Redis on its own terms. Four constructors, all taking the same useCluster / prefix:

// 1. redis-py-style URL (Optuna-identical)
new StackExchangeJournalRedisBackend("redis://localhost:6379");

// 2. keep the URL, tweak the derived ConfigurationOptions
new StackExchangeJournalRedisBackend("redis://localhost:6379", o =>
{
    o.ConnectTimeout = 5000;
    o.ClientName     = "my-app";
    o.ConnectRetry   = 3;
});

// 3. a ConfigurationOptions you built yourself (timeouts, retry policy, TLS certs, CommandMap, …)
var options = new ConfigurationOptions { EndPoints = { "localhost:6379" }, Ssl = true, ClientName = "my-app" };
new StackExchangeJournalRedisBackend(options);

// 4. an IConnectionMultiplexer you already own (pooled / shared / DI-managed — you keep its lifetime)
new StackExchangeJournalRedisBackend(existingMultiplexer);

The on-wire journal format is fixed regardless of how you connect, so the study stays byte-compatible with Python Optuna and the sibling backends whichever constructor you use.
