Best strategy for processing large CSV files in Apache Camel

If you use the Splitter EIP then you can use streaming mode which means Camel will process the file on a row by row basis.

from("file://data/inbox?noop=true&maxMessagesPerPoll=1&delay=5000")
  .split(body().tokenize("\n")).streaming()
    .unmarshal().bindy(BindyType.Csv, "com.ess.myapp.core")           
    .to("jms:rawTraffic");
