In Apache Beam , while using below P transformation -*fileio.MatchAll() and 
fileio.ReadMatches()*  dataflow job on load performance .( processing 48 
million resources)

For 2-3 minute  Throughput(element/sec) goes to zero and no element was 
processed during that time , it comes back again back to average normal 
(0.25/sec) of my job

In between these three minutes. There is no log from apache beam , if some IO 
error came or any warning.

Please check for any fileIO  known issue on  latest version of *apache-beam to 
2.23.0*
