/*

conch0 collects file info from the "testfiles" directory and concurrently
processes the files by decompressing the contents and then printing the
data or related error.

The "width" of concurrency is set by the constant "width". Parallelism is
scheduled properly regardless of CPUs available, and the processing will
be serial if only one CPU is available. Width, in this case, helps control
the maximum available goroutines to limit the usage of RAM (see heap
profile results).

 Available flags:
	-slow
		slow processing to clarify behavior
	-width int
		set concurrency width (default 8)

For convenience, a sub-command has been provided (conchtestdata) which will
generate the required files for processing.

Reading rows

mysqldriver reads data from the DB in a sequential order
which means the whole result set of first query must be read
before executing another one.

Number of read column's values and their types must match
with the number of columns in a query.

 rows, err := conn.Query("SELECT id, name, married FROM people")
 if err != nil {
 	// handle error
 }
 for rows.Next() { // always read all rows
 	id := rows.Int()       // order of columns must be preserved
 	name := rows.String()  // type of the column must match with DB type
 	married := rows.Bool() // all column's values must be read
 }
 if err = rows.LastError(); err != nil {
 	// handle error if any occurred during reading packets from DB
 }
