Detecting data loss
Dave Katz 2013-05-30, 21:57
Are there any hooks by which the Zookeeper server can signal that it has lost data?  It seems at least theoretically possible that when a server is reconciling its state with other servers that it could detect history truncation and signal it (even as crudely as throwing an exception).  This would provide a mechanism with which an elastic system could do last-ditch recovery when things fell apart.
