Usage

import { RocksDB } from "@nano-sql/adapter-rocksdb";
import { nSQL } from "@nano-sql/core";

nSQL().createDatabase({
    id: "my_db",
    mode: new RocksDB(),
    tables: [...]
}).then(...)

API

The RocksDB class accepts two optional constructor arguments.

path:string (optional)

Can be undefined to use default (__dirname), allows you to specify which folder to place the database folders into.

useIndex:boolean (optional)

Store the database index in webassembly memory. You get these tradeoffs:

• Dramatically improved offset/limit queries. (pagination)
• Dramatically improved index/count reads.
• Slightly reduces insert/delete performance.
• All keys across all tables must occupy less than ~4GB of space.
