A high performance redis cluster key slot calculator for node redis clients e.g. node_redis, ioredis and redis-clustr.
This also handles key tags such as somekey{actualTag}
.
Install
Install with NPM:
npm install cluster-key-slot --save
Usage
const calculateSlot = require('cluster-key-slot');
const calculateMultipleSlots = require('cluster-key-slot').generateMulti;
const slot = calculateSlot('test:key:{butOnlyThis}redis');
const slotForRedisMulti = calculateMultipleSlots([
'test:key:{butOnlyThis}redis',
'something:key45:{butOnlyThis}hello',
'example:key46:{butOnlyThis}foobar',
]);
