Package zipkin2.elasticsearch

Interface ElasticsearchStorage.LazyHttpClient

  • All Superinterfaces:
    java.lang.AutoCloseable, java.io.Closeable, java.util.function.Supplier<com.linecorp.armeria.client.HttpClient>
    Enclosing class:
    ElasticsearchStorage
    public static interface ElasticsearchStorage.LazyHttpClient
extends java.util.function.Supplier<com.linecorp.armeria.client.HttpClient>, java.io.Closeable
    This defers creation of an HttpClient. This is needed because routinely, I/O occurs in constructors and this can delay or cause startup to crash. For example, an underlying EndpointGroup could be delayed due to DNS, implicit api calls or health checks.
