使用IOREDIS在单个原子操作中发送许多BITOP

Question

我正在使用node.js使用ioredis client（@4.6.2），我需要做很多位操作（这不是彼此依赖的）。这样的东西：

import * as ioredis from "ioredis";
...
private readonly client: ioredis.Redis;
this.client = new ioredis("my_url");
...
await this.client.send_command("BITOP", "OR", "a_or_b", "a", "b");
await this.client.send_command("BITOP", "OR", "a_or_c", "a", "c");
await this.client.send_command("BITOP", "OR", "a_or_d", "a", "d");
await this.client.send_command("BITOP", "OR", "a_or_e", "a", "e");
// etc...

使用其他一些操作（例如setbit），我可以使用 Pipeline 对象及其exec()函数原子运行它们：

const pipeline: Pipeline = this.client.pipeline();
pipeline.setbit(a, 1, 1);
pipeline.setbit(a, 12, 0);
pipeline.setbit(b, 3,  1);
await pipeline.exec();

，但我找不到任何pipeline.bitop()和pipeline.send_command()功能。

有什么方法可以在原子操作中发送这些BITOP命令？谢谢

我终于设法使用了一系列命令作为构造函数的参数（如ioredis文档中所述），并且更快！

const result: number[][] = await this.redis.pipeline([
      ["bitop", "OR", "a_or_b", "a", "b"],
      ["bitop", "OR", "a_or_c", "a", "c"],
      ["bitop", "OR", "a_or_d", "a", "d"],
      ...
      ["bitcount", "a_or_b"],
      ["bitcount", "a_or_c"],
      ["bitcount", "a_or_d"],
      ...
]).exec();
