public static void filterLimitColFamilyRegex() {
  // TODO(developer): Replace these variables before running the sample.
  String projectId = "my-project-id";
  String instanceId = "my-instance-id";
  String tableId = "mobile-time-series";
  filterLimitColFamilyRegex(projectId, instanceId, tableId);
}

public static void filterLimitColFamilyRegex(
    String projectId, String instanceId, String tableId) {
  // A filter that matches cells whose column family satisfies the given regex
  Filter filter = new FamilyFilter(CompareOp.EQUAL, new RegexStringComparator("stats_.*$"));
  Scan scan = new Scan().setFilter(filter);
  readWithFilter(projectId, instanceId, tableId, scan);
