Whenever you need to share a code snippet, diff, logs, or a secret with another human being, the Pastebin service is invaluable. However, using public services such as [pastebin.com](https://pastebin.com), [privnote.com](https://privnote.com), etc. should be avoided when you're sharing data that should be available only for a selected audience (i.e., your company, private network). Instead of trusting external providers, you could host your own Pastebin service and take ownership of all your data!
**There are numerous [Pastebin implementations](https://github.com/awesome-selfhosted/awesome-selfhosted#pastebins) out there, why would you implement another one?**
This is a rust version of Pastebin service with [rocksdb](https://rocksdb.org/) database as storage. In addition to previously mentioned features it's worth to mention:
* all-in-one binary - all the data, including css/javascript files are compiled into the binary. This way you don't need to worry about external dependencies, it's all witin. (see: [std::include_bytes](https://doc.rust-lang.org/std/macro.include_bytes.html))
* [REST endpoint](https://rocket.rs/) - you can add/delete pastes via standard HTTP client (ie. curl)
* [RocksDB compaction filter](https://github.com/facebook/rocksdb/wiki/Compaction-Filter) - the expired pastes will be automatically removed by custom compaction filter
* [flatbuffers](https://google.github.io/flatbuffers/) - data is serialized with flatbuffers (access to serialized data without parsing/unpacking)
* GUI - the UI is a plain HTML with [Bootstrap JS](https://getbootstrap.com/), [jQuery](https://jquery.com/) and [prism.js](https://prismjs.com/)
* Encryption - password-protected pastes are AES encrypted/decprypted in the browser via [CryptoJS](https://code.google.com/archive/p/crypto-js/)
Pastebin builds only with `rust-nightly` version and requires `llvm` compiler to be present (rocksdb deps). To skip the build process, you can use the docker image.
docker run mkaczanowski/pastebin --address localhost --port 8000
```
### Client
```
alias pastebin="curl -q -L -d @- -o - http://localhost:8000/"
echo "hello World" | pastebin
http://localhost:8000/T9kGrI5aNkI4Z-PelmQ5U
```
## Nginx (optional)
The Pastebin service serves `/static` files from memory. To lower down the load on the service you might want to consider setting up nginx with caching and compression enabled, as shown here:
At first glance, the performance is pretty good. In the simplest scenario (5 concurrent clients), we can get up to `1000 rps` with the p95 response time at `6.59 ms` (`14986` total requests made).
As we add more concurrent clients, the rps drops a bit (`794 rps`) but still provides a good timing (p95 `38.67ms`) with high throughput at `47699` request made in 15s window (3x compared to Test 1).
