Best not to use them at all. If you must for some odd reason, use
backticks round the name.

No, readers block writers. This true of any system that only has read
and write locks

I understand that reads are locked by writes but nowhere does of
mention that reads also block reads. Boy queries y posted to the list
are selects.

How could they not? You can't simultaneously read and write the same
data -- the read would get half-written
My point is that on my process lists there are no writes being done at
that time only reads and actually only one read all other reads are
locked as well as writes. I've gone through every single one of the
queries in my processlist at any given time when more than 500 process
pile up and

Sure, that's because the reads are in line behind
I've extracted text from approx 1600 pdf files using pdftotext.exe and
inserted it into a table.
Now I see there are form feed characters in the field, and I would suspect

Any pointers appreciated.

What's the recommended method for high-availability setups?
I've currently got a master-master replication setup that I'm testing
but it doesn't quite seem as complete a solution as I had pictured.
When a failed server comes back online you still have to manually add
it based off of the line
Hello,
It isn't without its pros and cons (just like any other HA solution), but you

did you look at replication implementations using master/slave configuration?
