MESSAGE PARSING IN A DISTRIBUTED STREAM PROCESSING SYSTEM

Techniques for parsing a message comprising at least one data field are provided. One computer-implemented method comprises: determining, by an electronic device operatively coupled to a processing unit, a first model from a first category of data processing models; and determining, by the electronic device, a second model from a second category of data processing models, the second category being different from the first category. The computer-implemented method also comprises comparing, by the electronic device, performance of a first combined model of first and second models with performance of the first model; and selecting, by the electronic device, a target model for processing data from the first combined model and the first model based on the comparing.
