> PCollection<User> outTable = oldTable.union(newTable);
> Shard.shard(outTable,10).write(new AvroParquetFileTarget(tempOut+path), Target.WriteMode.OVERWRITE);
> However, I have another job which would read the output of above target output and use a field as the key , the job output looks like below

> there is extra suffix added to the key of the PTable, all of them
> should be RELEASE but not the RELEASEEASE bra bra
> If I remove the Shard, and keeps all the same, the output looks like normal
