How many keys can Redis store?
What is the maximum number of keys a single Redis instance can hold? and what is the max number of elements in a Hash, List, Set, Sorted Set? Redis can handle up to 232 keys, and was tested in practice to handle at least 250 million keys per instance. Every hash, list, set, and sorted…
What is the maximum number of keys a single Redis instance can hold? and what is the max number of elements in a Hash, List, Set, Sorted Set? Redis can handle up to 232 keys, and was tested in practice to handle at least 250 million keys per instance. Every hash, list, set, and sorted set, can hold 232 elements.Click to see full answer. Keeping this in view, is Redis a key value store?Redis is an in-memory non-relational key-value store (sometimes referred to as a data structure server). This means that it stores data based on keys and values — think of it as a giant dictionary that uses words and their definitions to store information.Similarly, how do I get all Redis keys? There are two ways to get all keys from the all databases in Redis. The first way is to list keys using –scan option and the second one is to get all keys using the KEYS command. In this regard, how much data can be stored in Redis? Unlike simplistic key-value data stores that offer limited data structures, Redis has a vast variety of data structures to meet your application needs. Redis data types include: Strings – text or binary data up to 512MB in size.What are Redis keys?Redis is a key-value database (also known as a key-value store) that uses a simple key/value method to store data. Strings are the simplest data type in Redis and are simple key/value entries. To save or fetch string data there are Redis SET and GET commands. Redis GET command returns a value assigned to a key.
