Dump

import { RedisDRS } from 'redis-drs';

const redis = new RedisDRS({ path: 'redis://localhost:6379/0' });
const data = redis.dump({ filePath: 'dump.csv', pattern: 'username:*' });

// Total keys is always the first item in the iterator
const total = (await data.next()).value as number;
console.log(`Total keys: ${total}`);

for await (const val of data) {
    // Here you can reach data stream copy
}

redis.disconnect();

Restore

import { RedisDRS } from 'redis-drs';

const redis = new RedisDRS({ path: 'redis://localhost:6379/0' });
const data = await redis.restore({
    filePath: 'dump.csv',
    useTtl: true,
    bulkSize: 1000,
});

// Total keys is always the first item in the iterator
const total = (await data.next()).value as number;
console.log(`Total keys: ${total}`);

for await (const val of data) {
    // Here you can reach data stream copy
}

redis.disconnect();

Sync

import { RedisDRS } from 'redis-drs';

const redis = new RedisDRS({ path: 'redis://localhost:6379/0' });
const data = await redis.sync({
    targetRedisOptions: { path: 'redis://localhost:6380/0' },
    pattern: 'username:*',
    useTtl: true,
});

// Total keys is always the first item in the iterator
