Disable automatic serialization

Your data is (de)serialized as json by default. This works for most use cases but you can disable it if you want: 
const redis = new Redis({
  // ...
  automaticDeserialization: false,
});

// or
const redis = Redis.fromEnv({
  automaticDeserialization: false,
});
This probably breaks quite a few types, but it’s a first step in that direction. Please report bugs and broken types here.

Keep-Alive

@upstash/redis optimizes performance by reusing connections wherever possible, reducing latency. This is achieved by keeping the client in memory instead of reinitializing it with each new function invocation. As a result, when a hot lambda function receives a new request, it uses the already initialized client, allowing for the reuse of existing connections to Upstash.
This functionality is enabled by default.
