This memcached engine provides multi-tenancy and isolation between other memcached engine instances.
It is designed to have minimal overhead while providing few constraints of its own.
That said, the ACL facilities are currently very limited and thus require SASL support and two security levels (admin, and everybody else).
You will need a storage-engine capable memcached and its included headers.
The easiest way to do this if you don't want to install memcached from source would be to just create a source tree and reference it.
For example, assume you keep all of your projects in
can do this:
cd ~/prog git clone -b engine git://github.com/dustin/memcached.git cd memcached ./config/autorun.sh ./configure make
Building the Bucket Engine
cd ~/prog git clone git://github.com/northscale/bucket_engine.git cd bucket_engine ./configure --with-memcached=$HOME/prog/memcached make
An example invocation using the bucket engine from your dev tree allowing every connecting user to automatically have his own isolated namespace within the default engine is as follows:
~/prog/memcached/memcached -v -S \ -E ~/prog/bucket_engine/.libs/bucket_engine.so \ -e engine=$HOME/prog/memcached/.libs/default_engine.so
The following configuration options are available for this engine.
An administrative user can be specified using the
This is the SASL authenticated user permitted to execute administrative commands (see scripts in the management directory for examples).
auto-create enabled, buckets are created automatically when
users first attempt to use them.
If true, a default bucket exists for unauthenticated users, or users
who don't have buckets created for them when
auto_create is disabled.
The contained engine is configured using the
engine parameter (see
the example above).
