# Redis Key Slot Calculator
|
|
|
|
A high performance redis cluster key slot calculator for node redis clients e.g. [node_redis](https://github.com/NodeRedis/node_redis), [ioredis](https://github.com/luin/ioredis) and [redis-clustr](https://github.com/gosquared/redis-clustr/).
|
|
|
|
This also handles key tags such as `somekey{actualTag}`.
|
|
|
|
## Install
|
|
|
|
Install with [NPM](https://npmjs.org/):
|
|
|
|
```
|
|
npm install cluster-key-slot --save
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const calculateSlot = require('cluster-key-slot');
|
|
const calculateMultipleSlots = require('cluster-key-slot').generateMulti;
|
|
|
|
// ...
|
|
|
|
// a single slot number
|
|
const slot = calculateSlot('test:key:{butOnlyThis}redis');
|
|
// Buffer is also supported
|
|
const anotherSlot = calculateSlot(Buffer.from([0x7b, 0x7d, 0x2a]));
|
|
|
|
// multiple keys - multi returns a single key slot number, returns -1 if any
|
|
// of the keys does not match the base slot number (base is defaulted to first keys slot)
|
|
// This is useful to quickly determine a singe slot for multi keys operations.
|
|
const slotForRedisMulti = calculateMultipleSlots([
|
|
'test:key:{butOnlyThis}redis',
|
|
'something:key45:{butOnlyThis}hello',
|
|
'example:key46:{butOnlyThis}foobar',
|
|
]);
|
|
```
|
|
|
|
## Benchmarks
|
|
|
|
`OLD` in these benchmarks refers to the `ioredis` crc calc and many of the other calculators that use `Buffer`.
