1. A method, comprising:

providing a plurality of composite keys for an event log, each of the composite keys composed of more than one column of a relational database and being a combination of a first time value and at least a portion of a plurality of attributes of a natural key;

wherein the processing device comprises a third processor that is different than the first and second processors, said distributing to control processing, by the first and second processors, of the distributed log lines,

the processing comprising i) sorting log lines based on the first time values, and ii) grouping the sorted log lines based on the natural keys,

wherein said processing produces an executable and linkable format (ELF) file.
