Vastly outdated - Not usable within KafkaStreams app anymore

[mirkoruether]

Hello Lenses team,
this library seems to not haven gotten much attention in the past few years, although it is still being mentioned in your latest docs here https://docs.lenses.io/5.5/guides/data-applications-integrations/external-apps/#register-via-jvm-client

Currently it is broken if you want to use it within your KafkaStreams app they way shown in "lenses-topology-example" repo.

The issue is related to io.lenses.topology.client.kafka.metrics.TopologyKafkaStreamsClientSupplier which still implements "getAdminClient" method instead of "getAdmin". See KIP-476: Add Java AdminClient Interface (deprecation of getAdminClient) and KAFKA-12630 (Removal of deprecated getAdminClient API in Kafka Version 3.0.0)

The fix would be quite easy I think (see below) and I was about to do it and hand it in via pull request, but looking at the versions of the libraries that this depends on, etc. I first would like to ask the question: Do you guys still plan support this library (as I said: still mentioned in latest Lenses docs) or is this thing dead and will stay dead?

Thanks in advance!

Warm regards,
Mirko Rüther

package io.lenses.topology.client.kafka.metrics;

    @Override
    public Admin getAdmin(final Map<String, Object> config) {
        return Admin.create(config);
    }

}
