Example 1 with GlobalConfigNotFoundException

use of com.couchbase.client.core.error.GlobalConfigNotFoundException in project couchbase-jvm-clients by couchbase.

the class Core method initGlobalConfig.

/**
 * Instructs the client to, if possible, load and initialize the global config.
 *
 * <p>Since global configs are an "optional" feature depending on the cluster version, if an error happens
 * this method will not fail. Rather it will log the exception (with some logic dependent on the type of error)
 * and will allow the higher level components to move on where possible.</p>
