Microstream integration into Helidon

This projects add Microstream support to Helidon.

The official Microstream documentation can be found here.

helidon-integrations-microstream

Adds basic support for Microstream

Prerequisites

Use the following maven dependency

<dependency>
	<groupId>io.helidon.integrations.microstream</groupId>
	<artifactId>helidon-integrations-microstream</artifactId>
</dependency>

API

Use the EmbeddedStorageManagerBuilder to create a Microstream instance:

EmbeddedStorageManager embeddedStorageManager = EmbeddedStorageManagerBuilder
		.builder()
		.build();

Configuration can either be done by the builders methods or by supplying a helidon configuration node

Config config = Config.create();

EmbeddedStorageManager embeddedStorageManager = EmbeddedStorageManagerBuilder
	.builder()
	.config(config)
	.build();

for a list of all possible properties see Microstream configuration properties

CDI extension for Microstream

the example below shows how to create a Microstream instance using a provided configuration.

private EmbeddedStorageManager storage;

@Inject
public YourConstructor(@MicrostreamStorage(configNode = "one.microstream.storage.greetings")EmbeddedStorageManager storage) {
		super();
		this.storage = storage;
}

helidon-integrations-microstream-cache

Adds basic support for the Microstream JCache implementation

Prerequisites

Use the following maven dependency

<dependency>         
	<groupId>io.helidon.integrations.microstream</groupId>
	<artifactId>helidon-integrations-microstream-cache</artifactId>
</dependency>

API

Use the CacheBuilder to create Microstream JCache instance:

Create a CacheConfiguration first

CacheConfiguration<Integer, String> cacheConfig = MicrostreamCacheConfigurationBuilder
	.builder(config.get("cache"), Integer.class, String.class).build();

Then build the cache

Cache<Integer, String> cache = CacheBuilder.builder(cacheConfig, Integer.class, String.class).build("myCache");

Configuration can either be done by the MicrostreamCacheConfigurationBuilder or by supplying a helidon configuration node

Config config = Config.create();

Cache<Integer, String> cache = CacheBuilder.create("myCache", config, Integer.class, String.class);

for a list of all possible properties see Microstream Cache configuration properties

CDI extension for Microstream

the example below shows how to create a Microstream-Cache instance using a provided configuration.

private Cache<Integer, String> cache;

@Inject
public YourConstructor(@MicrostreamCache(configNode = "one.microstream.cache", name = "myCache") Cache<Integer, String> cache) {
	this.cache = cache;
}

helidon-integrations-microstream-health

This module provides helpers to create basic health checks for Microstream

Prerequisites

Use the following maven dependency

<dependency>
	<groupId>io.helidon.integrations.microstream</groupId>
	<artifactId>helidon-integrations-microstream-health</artifactId>
</dependency>

Usage

Register an instance of MicrostreamHealthCheck to your server to provide a HealthCheck for a specific microstream instance.

helidon-integrations-microstream-metrics

This module provides helpers to create a set of default metrics for Microstream

Prerequisites

Use the following maven dependency

<dependency>
	<groupId>io.helidon.integrations.microstream</groupId>
	<artifactId>helidon-integrations-microstream-metrics</artifactId>
</dependency>

Usage

The MicrostreamMetricsSupport class provides a set of default metrics
