Input and output files that offload search pattern matching from clients to servers
A system enables client to convert a command, which specifies applying a search pattern to a data object that is stored by server, into at least one part of an input file, which specifies applying the search pattern to the data object that is stored by server, and to write at least one part of the input file to server, in response to receiving the command. The system reads the data object from server, in response to reading at least one part of the input file. The system generates a match result by applying the search pattern to the data object. The system writes at least one part of an output file, comprising the match result, to client, thereby enabling client to read at least one part of the output file and to convert at least one part of the output file into a response, comprising the match result, to the command.
