> Output of the explain() doesn't contain full information and in some cases
> can be truncated. Besides of that it saves info to a string in memory which
> can cause OOM. The ticket aims to solve the problem and dump info about query
> execution to a file. Need to add new method to queryExecution.debug which
> accepts a path to a file.
