Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

PerlIO::scalar(3pm)					 Perl Programmers Reference Guide				       PerlIO::scalar(3pm)

PerlIO::scalar - in-memory IO, scalar IO
my $scalar = ''; ... open my $fh, "<", $scalar or die; open my $fh, ">", $scalar or die; open my $fh, ">>", $scalar or die; or my $scalar = ''; ... open my $fh, "<:scalar", $scalar or die; open my $fh, ">:scalar", $scalar or die; open my $fh, ">>:scalar", $scalar or die;
A filehandle is opened but the file operations are performed "in-memory" on a scalar variable. All the normal file operations can be performed on the handle. The scalar is considered a stream of bytes. Currently fileno($fh) returns -1.
"PerlIO::scalar" only exists to use XSLoader to load C code that provides support for treating a scalar as an "in memory" file. One does not need to explicitly "use PerlIO::scalar". perl v5.18.2 2014-01-06 PerlIO::scalar(3pm)
