Configures how unique identifier lid strings are generated by @ember-data/store.

This configuration MUST occur prior to the store instance being created.

Takes a method which can expect to receive various data as its first argument and the name of a bucket as its second argument. Currently the second argument will always be record data should conform to a json-api Resource interface, but will be the normalized json data for a single resource that has been given to the store.

The method must return a unique (to at-least the given bucket) string identifier for the given data as a string to be used as the lid of an Identifier token.

This method will only be called by either getOrCreateRecordIdentifier or createIdentifierForNewRecord when an identifier for the supplied data is not already known via lid or type + id combo and one needs to be generated or retrieved from a proprietary cache.

data will be the same data argument provided to getOrCreateRecordIdentifier and in the createIdentifierForNewRecord case will be an object with only type as a key.

        
              import { setIdentifierGenerationMethod } from '@ember-data/store';

export function initialize(applicationInstance) {
  // note how `count` here is now scoped to the application instance
  // for our generation method by being inside the closure provided
  // by the initialize function
  let count = 0;

  setIdentifierGenerationMethod((resource, bucket) => {
    return resource.lid || `my-key-${count++}`;
  });
}
