 - **More Disk IO for Reads**: Since keys are now seperate from values, we have to make extra disk IO to fetch values? Yes, but since the key density now increases for each level (since we are only storing keys and value offsets in the sstable), we will most likely search fewer levels compared to LevelDB or RocksDB for thesame query. A significant portion of the LSM tree can also be cached in memory.

+Based on the introduction and efficiency of asynchronous IO at the OS kernel level e.g **io_uring** for the Linux kernel, VelarixDB is designed for asynchronous runtime. In this case Tokio runtime.
 Tokio allows for efficient and scalable asynchronous operations, making the most of modern multi-core processors. Frankly, most OS File System does not provide async API currently but Tokio uses a thread pool to offload blocking file system operations.
 This means that even though the file system operations themselves are blocking at the OS level, Tokio can handle them without blocking the main async task executor. Tokio might adopt [io_uring](https://docs.rs/tokio/latest/tokio/fs/index.html#:~:text=Currently%2C%20Tokio%20will%20always%20use%20spawn_blocking%20on%20all%20platforms%2C%20but%20it%20may%20be%20changed%20to%20use%20asynchronous%20file%20system%20APIs%20such%20as%20io_uring%20in%20the%20future.) in the future. (We haven't benchmarked the async version therefore this is unstable and might be removed in a future version)
