Bitmaps in Redis
Bitmaps are not an actual data type, but a set of bit-oriented operations defined on the String type which is treated like a bit vector. Since strings are binary safe blobs and their maximum length is 512 MB, they are suitable to set up to 2^32 different bits.
Basic Commands used in Bitmaps in Redis:
- SETBIT: This command is used to set the bit to 0 From 1, and 1 from 0.
- GETBIT: This command is used to returns the value of a bit at a given offset.
- BITOP: This command is used to perform bitwise operations against one or more strings.
How Redis Stores Bitmaps Data Types?
- Bitmaps are implemented as an array of bits.
- Redis provides bit-level operations to set, clear, and manipulate individual bits in a bitmap.
- Bitmaps are used for various applications, including analytics and tracking user behavior.
Complete Guide on Redis Data Types with Commands and Storage
Redis is an open-source, in-memory data store that supports various data types: such as String, Sets, Lists, Hashes, etc. to store data according to the needs of the user. These diverse data types make Redis versatile for caching, messaging, real-time analytics, and more.
