Examples of redis.clients.jedis.Jedis.hset()

redis.clients.jedis.Jedis.hset()
Set the specified hash field to the specified value.
If key does not exist, a new key holding a hash is created.
Time complexity: O(1) @param key @param field @param value @return If the field already exists, and the HSET just produced an updateof the value, 0 is returned, otherwise if a new field is created 1 is returned.

        // Get the Jedis instance that this key/value pair will be
        // written to -- (0,1)->0, (2-3)->1, ... , (10-11)->5
        Jedis j = jedisMap.get(key.getLastAccessMonth());


        // Write the key/value pair
        j.hset(MONTH_FROM_INT.get(key.getLastAccessMonth()), key
            .getField().toString(), value.toString());
      }
