Is this a good way to find elements starting with "cloudxlab" inside an rdd having strings as records: myrdd.collect().filter(_.startsWith("cloudxlab"))

Yes, it will be very efficient even if the data is big
No, The collect() on rdd brings data locally and then filters using local scala library fuction. Collect() will overflow the memory if data is big
