Can you run Redis instances on different ports?
Most folks seem to recommend running separate Redis instances on different ports (6379 and 6380). Why is this more commonly recommended over creating a second database? I’m not completely through the documentation yet, but most examples don’t really mention ‘selection of a Redis database’ when connecting.
How to create a cache name for Redis?
On the New Redis Cache page, configure the settings for your new premium cache. Enter a globally unique name. The cache name must be a string between 1 and 63 characters. The string can only contain numbers, letters, or hyphens. The name must start and end with a number or letter, and can’t contain consecutive hyphens.
How are keys distributed in a Redis cluster?
Per the Redis Keys distribution model documentation: The key space is split into 16384 slots. Each key is hashed and assigned to one of these slots, which are distributed across the nodes of the cluster. You can configure which part of the key is hashed to ensure that multiple keys are located in the same shard using hash tags.
When to use StackExchange.Redis cache 1.0.481?
If you’re using StackExchange.Redis, you must use 1.0.481 or later. You connect to the cache using the same endpoints, ports, and keys that you use when connecting to a cache where clustering is disabled. The only difference is that all reads and writes must be done to database 0.
Why do I need multiple Oracle database instances?
You might decide to run multiple Oracle database instances on a single multi-CPU server. A typical reason to do so would be server consolidation—using available hardware resources more efficiently. When running multiple instances on a single server, the instances compete for CPU.
How are database instances managed in Oracle Resource Manager?
Oracle Database provides a method for managing CPU allocations on a multi-CPU server running multiple database instances. This method is called instance caging. Instance caging and Oracle Database Resource Manager (the Resource Manager) work together to support desired levels of service across multiple instances.
What kind of data structures does Redis support?
It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, HyperLogLogs, geospatial indexes with radius queries, and streams. This reference architecture shows a typical six-node deployment of a Redis cluster on Oracle Cloud Infrastructure Compute instances.
