how many data get from source each batch

I read data from storm-kafka, and I knew

Config.TOPOLOGY_TRIDENT_BATCH_EMIT_INTERVAL_MILLIS

can set how long read a batch of data form kafka, but how read how many
data every time ?

Is there any configuration to set how many data get from source each batch?
