Hey there!

First, thanks for making this all happen, it helps me a lot in my daily work!

Secondly: Is there a chance, that you/we can get all forks on one table and see how this can be beneficial for the project? For example: You and also https://github.com/ngaut/rust-rocksdb seem to have made pretty good progress, but the branches are too diverged and I lack of knowledge to merge them my self.

So I try and shoutout to @ngaut, @BusyJay and @zhangjinpeng1987 to join the discussion if those two forks should be one again?

Hope that helps somehow ...

Cheers, Mario

I've hit an issue when I create a column family with a custom compare function and then try to re-open the same database. Since I can't pass in options to open_cf, my existing column familes are opened with the default options and I get an error.

This adds a new DB::open_cf_descriptors method that allows passing in Options for each column family, and a new ColumnFamilyDescriptor type was added to contain the congfiguration for each column family.

Fixes #336 Fixes #337 Related #294

As posted in #294, get_pinned has a huge performance advantage over get (current master)

test get_small                 ... bench:         156 ns/iter (+/- 9)

There are almost no case where you don't want a pinned get. So to make API simpler, we should always use pinned get and name it get. (#337 analyzes the control flow of current get, which internally uses pinned get as well). This PR updates get APIs to use pinned get, and deprecate get_pinned APIs.

Technically it's a breaking change as it adds lifetime, but similar to #294, its effect should be fairly small. Users who want a 'static struct could simply do slice.as_ref().to_owned(), and even doing such a clone is better than current get in terms of performance.

This function relies on the sequence number feature of RocksDB, and returns an iterator that yields every update made since that particular sequence. Since I saw how to add a function to rust-rocksdb earlier, I may submit a PR for this when the time comes (I'm not in a rush, just wanted to get this filed for now). Thanks for bringing RocksDB to Rust, it's been awesome.

This adopts pingcap/rust-rocksdb's SliceTransform approach, which changes the signature of transform_fn from &[u8] -> Vec<u8> to &'a [u8] -> &'a [u8] while removing the manual malloc call we're currently doing in transform_callback.

This significantly reduces memory usage, to the point where I wonder if this might actually be a memory leak if rocksdb isn't actually freeing the prefixes that we allocate in transform_callback. I might be wrong about this though—see the attached heap dump below.

Breaking change

The main use case for slice transforms is to create prefixes from existing keys, which you don't really need allocations for. However, in theory, the existing API could be used to create prefixes from completely different keys than what's passed in:

fn transform(k: &[u8]) -> Vec<u8> {
    "aa".as_bytes().to_vec()
}

This wouldn't be possible anymore with the API proposed in this PR.

Alternative API

PingCAP implements slice transforms as a trait where the transform function has a mutable receiver. This is a more flexible API in my opinion, but it would make the upgrade lift even more significant than what this PR already proposes. What do you think?

@spacejam, @ekmartin

Thank you for putting together and open-sourcing Rust RocksDB project. We at Exonum have been using it for more than a year and are interested in its further development.

Our team is grateful to you for reviewing and integrating our patches so far, however, it seems to us the project has ceased to be your top priority recently. For this reason, I suggest moving it under a new organization “rust-rocksdb” and giving more people permission to integrate changes and publish new versions of it on crates.io. In this way the project can evolve, enlarge its community, acquire better maintenance and improve in quality.

We understand it takes efforts maintaining an open-source project and would like to offer help with that. As you may know, members of Exonum team — @DarkEld3r, @ozkriff — have contributed various fixes and improvements to Rust RocksDB. Our team has expertise in running open-source projects in Rust, Exonum being the most prominent example.

Please consider further development of your project in a modified manner as suggested above and let us know your thoughts on the matter. You are free to contact our team members or me directly for discussion.

This is a bit of a follow-on from #144 but is different enough in scope

The native RocksDB column family API is a bit clunky and seems like an after thought. If users of rust-rocksdb prefer it this way, then that's fine, you can stop reading now.

If you're still with me, I am thinking that we can remove all PIGMED operations and remove the *_cf. The way we do this is make ColumnFamily the source for PIGMED operations. Or, we can shorten "ColumnFamily" to "Table" . So the API would look something like :

DB::open() -> DBResult   //which would enumerate and use all CFs by default
DB.get_table(cf_name: string) -> TableResult . // it would fetch the named table if it exists
DB.get_default_table() -> TableResult // if the user is living in the dark ages, use the default table

Table.put(key, val) 
Table.get(key)...
...

I have a crate rocks-cache that implements this API and it works quite nicely. We've been using it at work for a bit.

This function is probably the only unsafe public API of this library. The unsafe version is not super easy to use since it requires the user to carefully make sure the buffer is alive. For example, the following usage would be incorrect:

let mut opts = ReadOptions::default();
let upper_bound = b"k4".to_vec();
unsafe {
    opts.set_iterate_upper_bound(upper_bound);
}

A relatively easy way to make it safe is to store the buffer inside ReadOptions and store ReadOptions inside the iterator, so the buffer will not be dropped when the iterator is being used.

This pulls in https://github.com/ngaut/rust-rocksdb/pull/9. I've made changes to how the lifetime is defined on DBIterator and tweaked the tests to make them work without copying.

Part of #69

Motivation

Currently, RocksDB is linked dynamically. There's a few drawbacks to this approach:

1. End users of applications built using this wrapper must install exactly the same version of RocksDB that the application was built with. RocksDB is not included in many package managers at the moment so this either needs to be built from source or provided by the application author.
2. There's a problem with tcmalloc (used by RocksDB) clashing with jemalloc (used by Rust) that causes random segfaults
3. A developer using rust-rocksdb can choose which version of RocksDB to link with. This makes maintainability of rust-rocksdb more difficult as it must support mulltiple versions of RocksDB. This also makes it difficult to implement features that only exist a new version of RocksDB if it still has to support older versions.

These issues can be solved by statically linking RocksDB instead.

1. RocksDB is compiled in to the applications binary. End users don't need to install anything.
2. We can now control how RocksDB is built to make sure it doesn't pull in tcmalloc
3. Only one version of RocksDB can be used by the wrapper. This version is controlled the wrappers authors.

Implementation

A new sub crate has been added to this repo rocksdb-sys. This includes the FFI bindings and a build script for RocksDB/Snappy. It is based on the work in the Ethcore fork of this repo (https://github.com/ethcore/rust-rocksdb) which itself is based on the rocksdb-sys crate (https://github.com/jsgf/rocksdb-sys)

The build script is written in Rust and uses gcc-rs to talk to the the C++ compiler. It works on Windows (tested with VC++ 2015) and Linux.

RocksDB and Snappy's source code are pulled in with git submodules. This means that developers of rust-rocksdb will need to run git submodule init and git submodule update before developing. This does not affect users of the crate as the submodules are bundled within the crate at the point of packaging it. Users who directly link to the git repo in their cargo dependencies will take a little longer on the first build, submodules are handled automatically by cargo and are cached as well.

Updating RocksDB

RocksDB is currently pinned to the latest commit of the 4.13 maintenance branch.

Instead of using the makefile, we pass a list of .cc files in RocksDB to gcc-rs. The makefile is not used so that we can perform the build for both Linux and Windows platforms from the same build script.

The build script loads a list of .cc files from a text file rocksdb_lib_sources.txt. This is generated using a Makefile (that calls RocksDB's makefile to get the sources list) and committed into the git repo.

The process for updating RocksDB is as follows:

• cd into rocksdb-sys/rocksdb.
• git checkout the commit hash of the new version
• cd into rocksdb-sys
• run make gen_lib_sources
• Change the commit sha and date in rocksdb-sys/build_version.cc (it would be nice to automate this in build.rs)
• Test and commit those changes into git

There's a chance that they may change the build process/makefile causing the above steps to not work. I think it would be best to tackle these issues as they come; I don't expect they will be very common.

Alternative solutions

Pulling in rocksdb source code with git submodules

I chose to use git-submodules, despite concerns about the impact on build time when having to download the history of RocksDB.

• RocksDB will be bundled in the crate that is uploaded to crates.io so this won't afect most users
• Users who do reference the git repo from their Cargo.toml will have to download the RocksDB repo via the submodule, but this only happens on the first build as it is cached thereafter
• It takes less than a minute for me to download (10Mbit connection)
• I'm against making decisions based on performance concerns before actually trying it out

Alternative solution 1: Bundle the RocksDB source code in the repo

This is what the ethcore fork does

This would be my second choice if we find git-submodules to be a pain. I wanted to avoid this for the following reasons:

• Avoid bloat of this repo over time
• It's very tempting to make changes to the bundled version of RocksDB, but this will make maintainability a pain

Alternative solution 2: Download RocksDB during compile time

This is what the ngaut fork does.

I think this solution is horrible. You can find my thoughts about it in this comment: https://github.com/spacejam/rust-rocksdb/issues/69#issuecomment-256478979

Compiling RocksDB using a build.rs file

I decided to go with this as we can assume that all the platforms this project will be built on will have the ability to compile and run Rust code. The only dependency is a C++ compiler.

Alternative solution 1: Call the makefile from build.rs

I think this would be fine for Linux/Mac support but we will need something separate for Windows which uses CMake/MSBuild.

Alternative solution 2: Use a bash script instead of build.rs

This is an extension of "solution 1". It is what the ngaut fork does. I didn't like this for the following reasons:

• We would need to implement a separate build script for Windows
• We can already do a lot of the things that bash can do in Rust. But in a cross-platform way

Since TransactionDB is a subclass of StackableDB which is subclass of DB, there's no reason for the drop_cf function should be callable directly from TransactionDB.

The core of this change is a cast in transaction_db.rs:

self.inner as *mut ffi::rocksdb_t,

The PR also includes a test, but that's mostly copy-pasted from a similar test on DB, with the addition of testing for error when opening a previously deleted column family to make sure that the drop was actually successful.

When using rust-rocksdb with async_std and somehow keeping a reference to the DB inside a detached task, you can get SIGSEGV and SIGABRT.

A small reproducer:

#[async_std::test]
async fn db_fun() {
    let path = Path::new("/tmp/node01");
    if path.exists() {
        std::fs::remove_dir_all(path).expect("remove to succeed");
    }
    let mut db_opts = rocksdb::Options::default();
    db_opts.create_missing_column_families(true);
    db_opts.create_if_missing(true);

    let cf = "foo";
    let db = rocksdb::DB::open_cf(&db_opts, path, [cf]).expect("open to succeed");
    async_std::task::spawn(async move {
        let res = db
            .get_cf(&db.cf_handle(cf).expect("cf to be there"), "key")
            .expect("ok");
        assert!(res.is_none());
        async_std::task::sleep(std::time::Duration::from_millis(100)).await;
    });
}

Lots of variations of this succeed. With tokio for example, it doesn't occur. With detached threads, this doesn't occur. It seems to boil down to the static global PeriodicWorkScheduler being destroyed at the point where the detached task gets dropped.

Here is the field in question, it points to a static PeriodicWorkScheduler: https://github.com/facebook/rocksdb/blob/e656fa3d196c5b4c8a77255db1e6cd36a7ded348/db/db_impl/db_impl.h#L2532

Setting the field periodic_work_scheduler_ to nullptr after this line: https://github.com/facebook/rocksdb/blob/e656fa3d196c5b4c8a77255db1e6cd36a7ded348/db/db_impl/db_impl.cc#L484 fixes the issue.

It could be the order of static variables being cleaned up is a problem. The executor of async_std is kept inside a static var. Maybe the global PeriodicWorkScheduler is destroyed first?

It also seems to be fixed in rocksdb 7.7.0 and above, as it doesn't use a static PeriodicTaskScheduler anymore (although this has a static Timer in it).

So a big christmas wish for us would be an upgrade to rocksdb 7.7.3 :santa: :pray: :christmas_tree:

I got the below error when run cargo build --release. How can I fix it? cargo build -v --release

The following warnings were emitted during compilation:

hi，

I have a situation: 'seek' after many separate 'delete', the performance of 'seek' degrades very obvious. I did some search, there are some ways may help with the problem: 1、use 'deleterange' instead of many separate 'delete', this can help reducing "delete tombstone" but can only be used at some specific scenario, mine is not fit 2、'compact' periodicaly, it helps getting a relatively stable performance, but may cause some impact on my other scenarios. 3、use a 'CompactOnDeletionCollectorFactory', it triggers compaction when the ratio of delete reachs the specified value, but it could not be found and set at the lastest version.

so, is there any plan to add the interface?

Everytime I try to build a Rust project that uses rocksdb I get the same build errors:

I do have clang and llvm installed. I have even compiled clang + llvm from sources and installed them on the computer in an attempt to make sure the build system should work. I have the librocksdb-dev package installed as well. I am running on Debian Sid. I have entirely uninstalled librocksdb-dev llvm clang and even rust and then reinstalled them. I am unsure how to continue.
