#! # Features

default = ["compact"]
## Enables the `minimal`, `requests` and `graph-algo` features
compact = ["minimal", "requests", "graph-algo", "rayon"]
## Enables the `minimal`, `requests` and `graph-algo` features in single threaded mode
compact-single-threaded = ["minimal", "requests", "graph-algo"]
## Enables the `storage-sqlite` feature
minimal = ["storage-sqlite"]
## Enables the [Sqlite](https://www.sqlite.org/index.html) backend, also allows backup and restore with Sqlite data files.
storage-sqlite = ["dep:sqlite"]
## Enables the [RocksDB](http://rocksdb.org/) backend
storage-rocksdb = ["dep:cozorocks"]
## Enables the graph algorithms
graph-algo = ["dep:nalgebra"]
## Allows the utilities to make web requests to fetch data
requests = ["dep:minreq"]
## Uses jemalloc as the global allocator, can make a difference in performance
jemalloc = ["dep:tikv-jemallocator-global", "cozorocks?/jemalloc"]
## Enables io-uring option for the RocksDB storage
io-uring = ["cozorocks?/io-uring"]
## Enables the WASM target
wasm = ["uuid/js", "dep:js-sys"]
## Allows threading and enables the use of the `rayon` library for parallelizing algorithms
rayon = ["dep:rayon"]
## Disallows the use of threads
nothread = []

#! The following features are highly experimental:

## Enables the [Sled](https://github.com/spacejam/sled) backend
storage-sled = ["dep:sled"]
## Enables the [TiKV](https://tikv.org/) client backend
storage-tikv = ["dep:tikv-client", "dep:tokio"]

#! # Recommendation for features to enable
#!
#! Generally you will want the `storage-sqlite` and `graph-algo` features enabled,
#! unless your environment makes compiling them difficult. The backup/restore functionalities
#! are only available if `storage-sqlite` is on. Without `graph-algo` you cannot use any graph algorithms
#! (utilities are still available),
#! which could be OK if you only want to deal with pure Datalog.
#!
#! If having multiple threads
#! running in the background is undesirable, you can enable the `nothread` feature.
#!
#! The `rayon` feature enables some algorithms to make use of parallelism. This is desirable in most circumstances.
#! Naturally, it is incompatible with `nothread`.
#!
#! The `requests` feature allows the database to make outgoing HTTP requests to fetch data
#! into queries -- only enable it if you need it.
#!
#! The `wasm` feature simply patches some functions so that they can compile on WASM platform,
#! which lacks some std implementations at the moment. (On WASM you must also enable `nothread`).
#! This feature will not work on any other platform.
#!
#! The `jemalloc` feature only makes sense for desktop and servers. It could improve performance,
#! sometimes substantially, but you need to benchmark for your use case. It also tends to break
#! builds on untested platforms. None of our prebuilt binaries have it enabled.
#!
#! Enable `storage-rocksdb` if you expect high concurrency or want better performance than SQLite,
#! but note that RocksDB is much more resource-hungry and takes long to compile.
#!
#! The other storage options are just for experimentation. We do not recommend using them.
