SlateDB

SlateDB is an embedded storage engine that uses a log-structured merge-tree design and writes everything to cloud object storage. You include it as a library in your Rust applications, and it handles data storage through services like S3 or Google Cloud Storage.

The main advantage is unlimited storage capacity. Cloud storage can hold any amount of data without you managing servers or disks. It also provides automatic backups and can handle multiple readers at once, though only one writer at a time.

The trade-off is slightly higher response times compared to local disk storage. Write operations typically take 50-100 milliseconds. This makes SlateDB perfect for applications where cost and reliability matter more than ultra-fast response times.

Using SlateDB involves adding it to your Rust project and connecting it to object storage. Here are the steps:

• Add SlateDB to your project using Cargo by running cargo add slatedb tokio object-store in your terminal.

• Choose your object storage provider (Amazon S3, Google Cloud Storage, Azure Blob Storage, or others) and set up credentials and bucket access.

• Write code to open a database connection using the SlateDB library, pointing it to your storage bucket with proper settings.

• Use simple commands like put, get, and delete to store and retrieve data using key-value pairs.

• Configure settings like flush intervals, cache sizes, and compression options based on your needs.

• For production use, set up proper error handling and decide whether writes should wait for cloud confirmation or return immediately.

The library handles all the complex work of managing storage, caching, and keeping data organized.
