Class that extends the BaseStore class to interact with a Redis database. It provides methods for getting, setting, and deleting data, as well as yielding keys from the database.

Example

const store = new RedisByteStore({ client: new Redis({}) });
await store.mset([
[
"message:id:0",
new TextEncoder().encode(JSON.stringify(new AIMessage("ai stuff..."))),
],
[
"message:id:1",
new TextEncoder().encode(
JSON.stringify(new HumanMessage("human stuff...")),
),
],
]);
const retrievedMessages = await store.mget(["message:id:0", "message:id:1"]);
console.log(retrievedMessages.map((v) => new TextDecoder().decode(v)));
const yieldedKeys = [];
for await (const key of store.yieldKeys("message:id:")) {
yieldedKeys.push(key);
}
console.log(yieldedKeys);
await store.mdelete(yieldedKeys);
