Subject Trident paralellism
Date Tue, 03 Jan 2017 14:44:36 GMT
I have a Trident topology that processes tuples from an opaque Kafka spout. Three bolts write
different forms of processed output. Each form has a different record size. I have the same
parallelism and rotation policy applied to each of the three outputs, but this results in
two streams writing very small files to HDFS. I’m thinking of setting different parallelism
for each of the outputs. Is there any reason not to have different parallelism settings across
output bolts?
