Zookeeper Announcements for memcached
This fork adds zookeeper announcements to memcached. Our internal service discovery system uses ephemeral nodes on Zookeeper to publish the coordinates of a service (ip, port, type) to the platform.
The format of the announcements is hard coded and very Ness specific. However, we do plan to open source the actual discovery system soon.
This requires the zookeeper_st library from zookeeper.apache.org (we use zookeeper-3.3.3), the json-c library from http://oss.metaparadigm.com/json-c/ and libuuid from http://www.ossp.org/pkg/lib/uuid/. The latter two are bundled with Fedora Linux.
- --with-zookeeper= - Path to the zookeeper installation (or "yes" to use a systemwide installation)
- --with-libjson= - Path to the libjson installation (system wide installed on fedora)
- --with-libuuid= - Path to the libuuid installation (system wide installed on fedora)
Command line options
-Z or --zookeeper-connect-string - The Zookeeper connect string (:[,:])
-z or --zookeeper-node-path - The base path on Zookeeper for announcements (default: /ness/srvc)
-N or --ness-service-name - The service name to announce (default: memcached)
-T or --ness-service-type - The service type to announce (not announced by default)
-v enables zookeeper INFO logging
-vv enables zookeeper DEBUG logging
