There was a decent discussion of this during the hackathon:
http://lists.danga.com/pipermail/memcached/2007-July/004711.html
Seems interesting, don't recall if anyone was specifically against it.
The implementation details are a bit foggy, and someone has to go do it
still.
As of now, there's no way to do it.

Prem,
I see no point in implementing such this way (at least personally I
don't) for removing keys: executing a RegEx compilation is a stressing
operation and requires memory and CPU to execute it. The benefits you
get by non-hitting the database (that means not making the SQL
statement to be compiled and executed or, in case it's cached, just
executed) you will loose by compiling the RegEx and execute it.
My 2cents.

Hi All,
Is there a way to delete values based on a key specified as a regular
expression.
Example, I store some data in three formats and these keys are created as
key-1-xyz, key-2-xyz, key-3-xyz.
here xyz may take any value and is unique for all the three formats
Now, when there is any change in actual data, all the three formats
have to be deleted and at this point I have no idea about "xyz".
Is there a provision to delete objects by specifying a an expression
like : "key-%", so that every object whose hash key name starts with
"key-" will be deleted ?
Hope I am clear. Please get back to me for details.
Advance thanks and Regards,
Prem
