Our CMake build process produces tarball packages using the cpack TGZ target. This produces a server and client package with a file layout meant to match where the various artifacts go.

Meanwhile, the packages we include on the download page are a flat archive of various binaries produced by the build process. This include one regular package and one debug package with debug symbols for a few

Currently we don't have any mechanism to limit the maximum number of clients that could be handled simultaneously.

This feature should be designed properly. Here is some clue: https://redis.io/topics/clients#maximum-number-of-clients

Right now, to get an acceptable experience in dtlv, one has to use rlwrap, i.e. launch it like this rlwrap dtlv. It would be nice to integrate with jline3 library to have a better experience natively.

Right now, PebblesDB uses a lot of memory for the TableCache (caching metadata) and for the bloom filters used for each sstable.

We want to add a command line option for PebblesDB which would limit the total amount of memory used by PebblesDB for the TableCache and bloom filters.

When using the specified amount of memory, preference should be given first to the table cache, and then bloom

#[tokio::main]
async fn main() -> Result<()> {
    let txn_client = TransactionClient::new(vec!["127.0.0.1:2379"]).await?;
    let mut txn = txn_client.begin_optimistic().await.unwrap();
    let key = "aa".to_owned();
    txn.insert(key.clone(), "value".to_owned()).await.unwrap();
    txn.delete(key.clone()).await.unwrap();
    txn.commit().await.unwrap();
    Ok(())
}

There are no external core dependencies other than LZ4 and Snappy which are not used unless compression is configured. So they should be installable.

libraryDependencies += "io.swaydb" %% "lz4" % "version"
//OR 
libraryDependencies += "io.swaydb" %% "snappy" % "version"

For now we have to exclude

It would be better and easier to debug a program if the BytesEncoding and BytesDecoding traits could return any error type.

To do so we need to modify the Error enum and more specifically the Encoding and Decoding variants to wrap a Box<dyn Error>.
