The plugin works perfectly with in-memory cache for single-instance deployments. Redis is only needed for multi-replica deployments to share cache state. + +### Q: What happens if Redis goes down? + +**A:** The plugin implements a circuit breaker pattern. When Redis becomes unavailable: +1. Circuit breaker opens after threshold failures +2. Plugin falls back to in-memory cache +3. Periodically attempts to reconnect to Redis +4. Resumes Redis operations when connection restored + +### Q: Can I use Redis Cluster? + +**A:** Yes, Redis Cluster is supported. Configure with multiple node addresses and enable cluster mode in the configuration. + +### Q: What's the recommended cache mode? + +**A:** For production multi-replica deployments, use `hybrid` mode. It provides the best balance of performance and consistency. + +### Q: How much memory does Redis need? + +**A:** Memory requirements depend on: +- Number of active sessions +- Token sizes +- TTL configurations + +Typical sizing: +- Small (1-1000 users): 128MB +- Medium (1000-10000 users): 256MB-512MB +- Large (10000+ users): 1GB+ + +### Q: Can I use managed Redis services? + +**A:** Yes, the plugin works with: +- AWS ElastiCache +- Azure Cache for Redis +- Google Cloud Memorystore +- Redis Enterprise Cloud +- Any Redis-compatible service + +### Q: How do I monitor cache performance? + +**A:** Monitor these key metrics: +- Cache hit rate (target >90%) +- Redis latency (target <10ms p99) +- Circuit breaker state +- Connection pool utilization +- Memory usage + +### Q: Is data encrypted in Redis? + +**A:** Session data is encrypted before storing in Redis using the `sessionEncryptionKey`. Additionally, you can enable TLS for Redis connections. + +### Q: Can I migrate from memory to Redis without downtime? + +**A:** Yes, the migration can be done without downtime: +1. Deploy Redis +2. Enable Redis on instances gradually +3. Monitor for issues +4. Complete migration + +### Q: What Redis versions are supported? + +**A:** The plugin supports Redis 5.0 and later.

Here are the available options: + +#### 1. Streaming Credentials Provider (Highest Priority) - Experimental feature + +The streaming credentials provider allows for dynamic credential updates during the connection lifetime. This is particularly useful for managed identity services and token-based authentication. + +```go +type StreamingCredentialsProvider interface { + Subscribe(listener CredentialsListener) (Credentials, UnsubscribeFunc, error) +} + +type CredentialsListener interface { + OnNext(credentials Credentials) // Called when credentials are updated + OnError(err error) // Called when an error occurs +} + +type Credentials interface { + BasicAuth() (username string, password string) + RawCredentials() string +} +``` + +Example usage: +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + StreamingCredentialsProvider: &MyCredentialsProvider{}, +}) +``` + +**Note:** The streaming credentials provider can be used with [go-redis-entraid](https://github.com/redis/go-redis-entraid) to enable Entra ID (formerly Azure AD) authentication. This allows for seamless integration with Azure's managed identity services and token-based authentication. + +Example with Entra ID: +```go +import ( + "github.com/redis/go-redis/v9" + "github.com/redis/go-redis-entraid" +) + +// Create an Entra ID credentials provider +provider := entraid.NewDefaultAzureIdentityProvider() + +// Configure Redis client with Entra ID authentication +rdb := redis.NewClient(&redis.Options{ + Addr: "your-redis-server.redis.cache.windows.net:6380", + StreamingCredentialsProvider: provider, + TLSConfig: &tls.Config{ + MinVersion: tls.VersionTLS12, + }, +}) +``` + +#### 2. Context-based Credentials Provider + +The context-based provider allows credentials to be determined at the time of each operation, using the context. + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + CredentialsProviderContext: func(ctx context.Context) (string, string, error) { + // Return username, password, and any error + return "user", "pass", nil + }, +}) +``` + +#### 3. Regular Credentials Provider + +A simple function-based provider that returns static credentials. + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + CredentialsProvider: func() (string, string) { + // Return username and password + return "user", "pass" + }, +}) +``` + +#### 4. Username/Password Fields (Lowest Priority) + +The most basic way to provide credentials is through the `Username` and `Password` fields in the options. + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + Username: "user", + Password: "pass", +}) +``` + +#### Priority Order + +The client will use credentials in the following priority order: +1. Streaming Credentials Provider (if set) +2. Context-based Credentials Provider (if set) +3. Regular Credentials Provider (if set) +4. Username/Password fields (if set) + +If none of these are set, the client will attempt to connect without authentication. + +### Protocol Version + +The client supports both RESP2 and RESP3 protocols. You can specify the protocol version in the options: + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + Password: "", // no password set + DB: 0, // use default DB + Protocol: 3, // specify 2 for RESP 2 or 3 for RESP 3 +}) +``` + +### Connecting via a redis url + +go-redis also supports connecting via the +[redis uri specification](https://github.com/redis/redis-specifications/tree/master/uri/redis.txt). +The example below demonstrates how the connection can easily be configured using a string, adhering +to this specification. + +```go +import ( + "github.com/redis/go-redis/v9" +) + +func ExampleClient() *redis.Client { + url := "redis://user:password@localhost:6379/0?protocol=3" + opts, err := redis.ParseURL(url) + if err != nil { + panic(err) + } + + return redis.NewClient(opts) +} + +``` + +### Instrument with OpenTelemetry + +```go +import ( + "github.com/redis/go-redis/v9" + "github.com/redis/go-redis/extra/redisotel/v9" + "errors" +) + +func main() { + ... + rdb := redis.NewClient(&redis.Options{...}) + + if err := errors.Join(redisotel.InstrumentTracing(rdb), redisotel.InstrumentMetrics(rdb)); err != nil { + log.Fatal(err) + } +``` + + +### Buffer Size Configuration + +go-redis uses 32KiB read and write buffers by default for optimal performance. For high-throughput applications or large pipelines, you can customize buffer sizes: + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + ReadBufferSize: 1024 * 1024, // 1MiB read buffer + WriteBufferSize: 1024 * 1024, // 1MiB write buffer +}) +``` + +### Advanced Configuration + +go-redis supports extending the client identification phase to allow projects to send their own custom client identification. + +#### Default Client Identification + +By default, go-redis automatically sends the client library name and version during the connection process. This feature is available in redis-server as of version 7.2. As a result, the command is "fire and forget", meaning it should fail silently, in the case that the redis server does not support this feature. + +#### Disabling Identity Verification + +When connection identity verification is not required or needs to be explicitly disabled, a `DisableIdentity` configuration option exists. +Initially there was a typo and the option was named `DisableIndentity` instead of `DisableIdentity`. The misspelled option is marked as Deprecated and will be removed in V10 of this library. +Although both options will work at the moment, the correct option is `DisableIdentity`. The deprecated option will be removed in V10 of this library, so please use the correct option name to avoid any issues. + +To disable verification, set the `DisableIdentity` option to `true` in the Redis client options: + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + Password: "", + DB: 0, + DisableIdentity: true, // Disable set-info on connect +}) +``` + +#### Unstable RESP3 Structures for RediSearch Commands +When integrating Redis with application functionalities using RESP3, it's important to note that some response structures aren't final yet. This is especially true for more complex structures like search and query results. We recommend using RESP2 when using the search and query capabilities, but we plan to stabilize the RESP3-based API-s in the coming versions. You can find more guidance in the upcoming release notes. + +To enable unstable RESP3, set the option in your client configuration: + +```go +redis.NewClient(&redis.Options{ + UnstableResp3: true, + }) +``` +**Note:** When UnstableResp3 mode is enabled, it's necessary to use RawResult() and RawVal() to retrieve a raw data. + Since, raw response is the only option for unstable search commands Val() and Result() calls wouldn't have any affect on them: + +```go +res1, err := client.FTSearchWithArgs(ctx, "txt", "foo bar", &redis.FTSearchOptions{}).RawResult() +val1 := client.FTSearchWithArgs(ctx, "txt", "foo bar", &redis.FTSearchOptions{}).RawVal() +``` + +#### Redis-Search Default Dialect + +In the Redis-Search module, **the default dialect is 2**. If needed, you can explicitly specify a different dialect using the appropriate configuration in your queries. + +**Important**: Be aware that the query dialect may impact the results returned. If needed, you can revert to a different dialect version by passing the desired dialect in the arguments of the command you want to execute. +For example: +``` + res2, err := rdb.FTSearchWithArgs(ctx, + "idx:bicycle", + "@pickup_zone:[CONTAINS $bike]", + &redis.FTSearchOptions{ + Params: map[string]interface{}{ + "bike": "POINT(-0.1278 51.5074)", + }, + DialectVersion: 3, + }, + ).Result() +``` +You can find further details in the [query dialect documentation](https://redis.io/docs/latest/develop/interact/search-and-query/advanced-concepts/dialects/). + +#### Custom buffer sizes +Prior to v9.12, the buffer size was the default go value of 4096 bytes. Starting from v9.12, +go-redis uses 32KiB read and write buffers by default for optimal performance. +For high-throughput applications or large pipelines, you can customize buffer sizes: + +```go +rdb := redis.NewClient(&redis.Options{ + Addr: "localhost:6379", + ReadBufferSize: 1024 * 1024, // 1MiB read buffer + WriteBufferSize: 1024 * 1024, // 1MiB write buffer +}) +``` + +**Important**: If you experience any issues with the default buffer sizes, please try setting them to the go default of 4096 bytes. + +## Contributing +We welcome contributions to the go-redis library!
