deno_redis

perform the test

RUST_BACKTRACE=full deno run --allow-all test.ts

The problem record

The deno load plug-in has no tokio runtime in it。issue

The solution

A new thread with tokio runtime interacts with dispatch_op for mpsc

question

Tested asynchronous performance is not as good as synchronous performance。So it's synchronized，It will be changed to asynchronous later. Here is the original design, but the performance does not improve

If you can do better through asynchrony, please contact me

test

Small sample

node

const redis = require("redis");
const client = redis.createClient();
const time = new Date();
const param = ["key1", "foo", "key2", "foo", 
                    "key3", "foo", "key4", "foo", "key5", 
                    "foo", "key6", "foo", "key7", "foo", 
                    "key7", "foo", "key8", "foo", "key9", "foo"];
client.hmset("test", param, function (err, res) {
  console.log('time',new Date() - time);
});

average: 10ms

deno

  const client: RedisClient = new RedisClient({
    host: '127.0.0.1',
    port: 6379,
    db: 0,
  });
  const param = ["key1", "foo", "key2", "foo", 
                    "key3", "foo", "key4", "foo", "key5", 
                    "foo", "key6", "foo", "key7", "foo", 
                    "key7", "foo", "key8", "foo", "key9", "foo"];
  const time = new Date().getTime();
  await client.connection.hmset("test", param);
  console.log(new Date().getTime() - time);

average: 1ms

Large benchmark
