		* <h3>Job execution mode</h3>
		*
		*
		* <p>
		* This executor is able to process queries coming from a synchronous job (the result must be written directly in the HTTP response)
		* and from an asynchronous job (the result must be written, generally, in a file). Two start(...) functions let deal with
		* the differences between the two job execution modes: {@link #start(AsyncThread)} for asynchronous jobs
		* and {@link #start(Thread, String, TAPParameters, HttpServletResponse)} for synchronous jobs.
		* </p>
		*
		*
		* <h3>Input/Output formats</h3>
		*
		*
		* <p>Uploaded tables must be provided in VOTable format.</p>
		*
		*
		* <p>
		* Query results must be formatted in the format specified by the user in the job parameters. A corresponding formatter ({@link OutputFormat})
		* is asked to the description of the TAP service ({@link ServiceConnection}). If none can be found, VOTable will be chosen by default.
		* </p>
		*
		*
		* <h3>Executor customization</h3>
		*
		*
		* <p>It is totally possible to customize some parts of the ADQL query processing. However, the main algorithm must remain the same and is implemented
		* by {@link #start()}. This function is final, like {@link #start(AsyncThread)} and {@link #start(Thread, String, TAPParameters, HttpServletResponse)},
		* which are just preparing the execution for {@link #start()} in function of the job execution mode (asynchronous or synchronous).
		* </p>
		*
		*
		* <p><i>Note:
		* {@link #start()} is using the Template Method Design Pattern: it defines the skeleton/algorithm of the processing, and defers some steps
		* to other functions.
		* </i></p>
		*
		*
		* <p>
		* So, you are able to customize almost all individual steps of the ADQL query processing: {@link #parseADQL()}, {@link #executeADQL(ADQLQuery)} and
		* {@link #writeResult(TableIterator, OutputFormat, OutputStream)}.
		* </p>
		*
		*
		* <p><i>Note:
		* Note that the formatting of the result is done by an OutputFormat and that the executor is just calling the appropriate function of the formatter.
		* </i></p>
		*
		*
		* <p>
		* There is no way in this executor to customize the upload. However, it does not mean it can not be customized.
		* Indeed you can do it easily by extending {@link Uploader} and by providing the new class inside your {@link TAPFactory} implementation
		* (see {@link TAPFactory#createUploader(DBConnection)}).
		* </p>
