Bucket4j and infinispan

[git-volver]

Hi,
Congratulations about this superb API.
I am in trouble to use it in my project, and would be glad for some help.
The infinispan API is already been used in my web project in "Embedded mode" with wildfly12 and java8. So, there is a infinispan_config.xml with a "cache-container" element used globally in application.
Can I put another context-initializer element with class="io.github.bucket4j.grid.infinispan.serialization.Bucket4jProtobufContextInitializer"
together the other existing in there?
And the obvious difficulty for me is how to use the code in the example you suggested in
https://bucket4j.com/8.2.0/toc.html#bucket4j-infinispan

`3.4.4. Example of Bucket instantiation
org.infinispan.functional.FunctionalMap.ReadWriteMap<K, byte[]> map = ...;
private static final InfinispanProxyManager proxyManager = new InfinispanProxyManager(map);

...
BucketConfiguration configuration = BucketConfiguration.builder()
.addLimit(Bandwidth.simple(1_000, Duration.ofMinutes(1)))
.build(key, configuration);

Bucket bucket = proxyManager.builder().build(configuration);`

how to instantiate the map variable?

My intention is to control the rate limit from IP to certain request paths (like public domains) inside a servlet filter.

Cheers, and thanks by advanced.

Hello @git-volver

Can I put another context-initializer element with class="io.github.bucket4j.grid.infinispan.serialization.Bucket4jProtobufContextInitializer"

According to Infinispan documentation it is possible https://infinispan.org/docs/stable/titles/encoding/encoding.html#registering-sci-embedded-caches_marshalling

how to instantiate the map variable?

If you have an instance of org.infinispan.Cache then initialization of finctional map is trivial:

private static ReadWriteMap<String, byte[]> toMap(Cache<String, byte[]> cache) {
        FunctionalMapImpl<String, byte[]> functionalMap = FunctionalMapImpl.create(cache.getAdvancedCache());
        return ReadWriteMapImpl.create(functionalMap);
}

See this test if something unclear according to map instantiation https://github.com/bucket4j/bucket4j/blob/master/bucket4j-infinispan-all/bucket4j-infinispan/src/test/java/io/github/bucket4j/grid/infinispan/InfinispanTest.java
