Default Iglu Client Resolver has no cache #122

Closed paulboocock closed 1 year ago

paulboocock commented 1 year ago

When running Micro with no configuration (docker run -p 9090:9090 snowplow/snowplow-micro:1.3.4) the responses are significantly slower than when run with the --iglu flag and the example iglu.json.

This is due to iglu.json having a default cacheSize of 500, but the built in default Iglu Resolve has None: https://github.com/snowplow-incubator/snowplow-micro/blob/master/src/main/scala/com.snowplowanalytics.snowplow.micro/ConfigHelper.scala#L48

We can pass a ResolverCache here instead of None, probably with a cache of 500 like the default iglu.json, which should improve performance when running Micro with zero config.

Enrich 3.6.1 made quite big changes to how it uses Iglu Client. In upgrading Micro to use 3.6.1 it became natural to add a cache at the same time.
