do you need to set the limit on the query here? otherwise gtNextQuery will return the wrong thing

hmm this should be handled by advnace and getNextQuery needs to be called after advance:

Query query = Query.create(...).range("a", "z");
Query.QueryPaginator paginator = query.createQueryPaginator(100);
ByteString lastSeenRowKey = ByteString.EMPTY;
while (paginator.advance(lastSeenRowKey)) {
    List<Row> rows = client.readRowsCallable().all().call(paginator.getNextQuery());
      for (Row row : rows) {
      // do some processing
     lastSeenRow = row;
    }
 }

this.hasOverallLimit = query.builder.getRowsLimit() > 0;
