How to do Mass insertion in Redis using JAVA?

Hi I need to do multiple insertions of the form

SADD key value

I have the key value pair and needed to know how to perform mass insertions using JAVA . I have written a file in the Redis Protocol. How to proceed further

Solution

If you have inputs written to Redis protocol format then why don't just use pipe mode of redis-cli or nc? It's explained from http://redis.io/topics/mass-insert.

If you have mass (key, value) inputs then you can use Jedis to perform sadd with pipelining to get higher performance.

Below example assumes that iter (Iterator) has elements each item is key"\t"value form.

try (Jedis jedis = new Jedis(host, port)) {
  Pipeline pipeline = jedis.pipelined();
  while (iter.hasNext()) {
    String[] keyValue = iter.next().split("\t");
    pipeline.sadd(keyValue[0], keyValue[1]);
    // you can call pipeline.sync() and start new pipeline here if you think there're so much operations in one pipeline
  }
  pipeline.sync();
}
