> Java Distributed lock library with database migration capabilities

Look for details in the [documentation](https://coditory.github.io/sherlock-distributed-lock/).

- **[supports multiple databases](https://coditory.github.io/sherlock-distributed-lock/connectors/)** - [SQL databases](https://coditory.github.io/sherlock-distributed-lock/connectors/sql/), [MongoDB](https://coditory.github.io/sherlock-distributed-lock/connectors/mongo/) and more

- **[multiple types of locks](https://coditory.github.io/sherlock-distributed-lock/locks)** - multiple ways to acquire a lock: reentrant, single-entrant and more

- **[basic DB migration](https://coditory.github.io/sherlock-distributed-lock/migrator)** - provides database migration process based on locks. No need for another library.

- **[synchronous and reactive API](https://coditory.github.io/sherlock-distributed-lock/api)** - exposes synchronous and reactive API (supports synchronous calls, Reactor, RxJava, Kotlin coroutines)

- **minimal set of dependencies** - the main dependency is a database driver

## Sample usage

Add dependency to `build.gradle`:

```groovy

dependencies {

  implementation "com.coditory.sherlock:sherlock-mongo:$version"

}

```

Create synchronous MongoDB backed lock:

```java

// Get mongo collection

// You can also use other DB or reactive API

MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017/sherlock");

MongoCollection collection = mongoClient

    .getDatabase("sherlock")

    .getCollection("locks");

// Create sherlock

Sherlock sherlock = MongoSherlock.create(collection);

// Create a lock

DistributedLock lock = sherlock.createLock("sample-lock");

// Acquire a lock, run action and finally release the lock

lock.runLocked(() -> System.out.println("Lock granted!"));

```
