Azure Managed Redis fundamentals 5 commands Aliases: Redis keyspace, Redis DB, Redis cache database Quick peek Open full term page

Databases verified Redis Enterprise Redis Enterprise is the commercial Redis platform used by Azure Managed Redis and Azure Cache for Redis Enterprise tiers. It adds managed clustering, high-throughput shard placement, modules, active geo-replication, persistence options, and enterprise operations around the familiar Redis API. Cache fundamentals 5 commands Aliases: Redis Enterprise software, Enterprise Redis Quick peek Open full term page

Databases verified Redis Enterprise cache A Redis Enterprise cache is an Azure cache instance running on Redis Enterprise rather than basic open-source Redis nodes. In Azure Cache for Redis Enterprise tiers, it provides clustered data nodes, quorum behavior, Enterprise/Enterprise Flash SKUs, modules, persistence, and active geo-replication for demanding workloads. Azure Managed Redis intermediate 5 commands Aliases: Azure Cache for Redis Enterprise, Enterprise Redis cache, Enterprise cache Quick peek Open full term page

Databases verified Redis eviction Redis eviction is the Redis behavior that removes keys when memory pressure reaches the configured limit. Azure Managed Redis and Azure Cache for Redis expose eviction through memory policies, TTL behavior, metrics, and diagnostics so teams can decide which cached data may disappear safely. Azure Managed Redis intermediate 5 commands Aliases: No aliases yet Quick peek Open full term page

Databases verified Redis eviction policy A Redis eviction policy is the configured maxmemory rule that decides which keys are eligible for removal when Redis needs memory. Azure supports policies such as volatile-lru, allkeys-lru, random, TTL-based, LFU, and noeviction depending on Redis service, tier, and database configuration. Cache and in-memory data intermediate 5 commands Aliases: No aliases yet Quick peek Open full term page

Databases verified Redis import export Redis import/export moves cache data as Redis Database snapshots between Azure Redis instances and Azure Storage blobs. Azure Managed Redis can import from page or block blobs and export to block blobs, supporting migration, prepopulation, data movement, and controlled operational transfers. Azure Managed Redis intermediate 5 commands Aliases: No aliases yet Quick peek Open full term page

Databases verified Redis keyspace Redis keyspace is the live set of keys, values, expirations, and metadata inside a Redis database. In Azure Redis services, it shows up through database selection, key naming, TTL behavior, and optional keyspace notifications that publish events when keys change or expire. Data platform intermediate 5 commands Aliases: Redis namespace, Redis keys, Redis key namespace, keyspace notifications Quick peek Open full term page

Databases verified Redis module A Redis module extends Redis beyond core commands with extra data structures or query capabilities. Azure Managed Redis supports modules such as RediSearch, RedisBloom, RedisTimeSeries, and RedisJSON; modules are selected during cache creation and managed by the service rather than loaded manually afterward. Azure Managed Redis intermediate 5 commands Aliases: Redis extensions, Redis modules, RediSearch, RedisJSON, RedisBloom, RedisTimeSeries Quick peek Open full term page

Databases verified Redis passive geo-replication Redis passive geo-replication links two Premium Azure Cache for Redis instances, usually across Azure regions. The primary accepts reads and writes, replicated data flows to a read-only secondary, and failover is an operator-driven disaster recovery action rather than automatic traffic switching. Azure Managed Redis advanced 5 commands Aliases: passive Redis geo-replication, Azure Cache Redis geo replication, Redis server link, read-only Redis secondary Quick peek Open full term page

Databases field-manual-complete Redis persistence Redis persistence is the option that lets a Redis cache survive more than memory loss. Normal Redis is often treated as disposable because data lives in memory and can be rebuilt from a database. Persistence changes that assumption by saving snapshots or append-only changes so the cache can be restored after a serious failure. In Azure, it belongs with workload recovery planning, not routine backup exports. You still decide which data is safe to keep in Redis and which must remain in a durable database. Cache and in-memory data fundamentals 5 commands Aliases: Redis data persistence, RDB persistence, AOF persistence, Redis persisted cache Quick peek Open full term page

Databases field-manual-complete Redis private endpoint A Redis private endpoint gives your application a private IP path to Redis inside an Azure virtual network. Instead of letting clients reach the cache through its public endpoint, you attach a private endpoint to a subnet and connect through Private Link. The cache remains a managed Azure service, but traffic from approved networks resolves to private address space. This is most useful when security policy, compliance rules, or network design require Redis to behave like an internal dependency rather than an internet-exposed service. Cache and in-memory data intermediate 5 commands Aliases: Redis Private Endpoint, Azure Redis private endpoint, Redis endpoint over Private Link, Private Redis endpoint Quick peek Open full term page

Databases field-manual-complete Redis private link Redis private link is the private connectivity pattern behind a Redis private endpoint. Private Link is the Azure capability that connects a private endpoint in your virtual network to the managed Redis service. The application still uses the Redis hostname, but DNS resolves it to a private address when configured correctly. Think of private link as the service relationship and private endpoint as the concrete network interface. It matters when your architecture needs private data-service access without self-hosting Redis inside the virtual network. Cache intermediate 5 commands Aliases: Redis Private Link, Private Link for Redis, Azure Redis Private Link, Redis private connectivity Quick peek Open full term page

Databases field-manual-complete Redis TLS port Redis TLS port is the connection path your Redis client uses when traffic must be encrypted. In many Azure Cache for Redis deployments, TLS clients use port 6380 while the old non-TLS port is 6379. Azure Managed Redis uses port 10000 for both TLS and non-TLS modes. The exact port matters because client libraries, firewall rules, private endpoints, health probes, and connection strings must agree. A wrong port can look like a Redis outage even when the cache is healthy. Azure Managed Redis intermediate 5 commands Aliases: Redis SSL port, Redis encrypted port, Azure Redis TLS endpoint, Redis port 6380 Quick peek Open full term page

Databases field-manual-complete Redis vector similarity search Redis vector similarity search lets Redis answer questions like “which stored items are most similar to this embedding?” Instead of matching only exact words, applications store vectors that represent meaning, images, products, documents, or events. Redis indexes those vectors and returns nearby results quickly. In Azure, this is useful when a team wants low-latency AI retrieval or recommendations close to the application cache. It is not a magic model; the quality still depends on embeddings, index design, metadata filters, and refresh discipline. Azure Managed Redis advanced 5 commands Aliases: Redis vector search, Redis VSS, RediSearch vector search, Redis KNN search Quick peek Open full term page

Databases verified Redis cache shard A Redis cache shard is a slice of the cache. Instead of forcing every key, session, counter, and hot lookup through one Redis process, the cache can divide data across multiple shards. Each shard owns part of the keyspace, so the workload has more room and more processing capacity. For a learner, the important point is simple: sharding helps a cache grow horizontally, but it also makes key design, client compatibility, monitoring, and operational change control more important. Cache and in-memory data fundamentals 4 commands Aliases: Redis shard, cache shard, Redis partition Quick peek Open full term page

Databases verified Redis cache SKU A Redis cache SKU is the size and capability package you buy for the cache. It answers questions like how much memory the cache has, what performance level it can provide, which high-availability or scaling features are available, and how much it will cost. For Azure teams, SKU is not just a billing label. It is a design decision that affects latency, resilience, migration options, monitoring expectations, and whether the cache can support the application when traffic grows. Cache and in-memory data fundamentals 4 commands Aliases: Redis SKU, cache SKU, Redis size Quick peek Open full term page

Databases verified Redis cache tier A Redis cache tier is the broad class of cache capability, while the SKU is the exact purchasable size inside that class. The tier tells you what kind of workload the cache is meant for: simple development, production high availability, larger scale, flash-backed capacity, or a managed enterprise-style Redis deployment. For learners, tier is the decision that says what features and operating expectations are on the table before anyone argues about the exact memory size. Cache intermediate 4 commands Aliases: Redis tier, cache tier, Redis performance tier Quick peek Open full term page

Databases verified Redis clustering Redis clustering means the cache is not one giant bucket handled by one Redis process. The keyspace is divided across multiple Redis processes, often called shards, so the service can use more memory and processing power. Applications still talk to Redis, but the client library may need to understand where keys live. Clustering is useful for scale, but it changes how developers think about multi-key commands, hot keys, testing, failover, and operational monitoring. Cache and in-memory data intermediate 4 commands Aliases: Redis cluster, clustered Redis, Redis scale out Quick peek Open full term page

Databases verified Redis connection resilience Redis connection resilience is the difference between a brief cache hiccup and a full application outage. Redis clients can lose connections during maintenance, failover, network changes, private endpoint issues, TLS problems, high server load, or application restarts. A resilient application reconnects carefully, retries with limits, avoids flooding Redis, and can fall back to the durable source of truth when needed. The goal is not to pretend Redis never fails; the goal is to make cache failure boring and survivable. Azure Managed Redis intermediate 4 commands Aliases: Redis reconnect resilience, Redis client resilience, Redis timeout strategy Quick peek Open full term page

AI and Machine Learning expanded Semantic cache A semantic cache stores previous prompts and responses with vector representations so later requests with similar meaning can reuse a cached response. In Azure, this pattern is used with services such as API Management and Azure Managed Redis to reduce latency, backend load, and LLM calls.
