Subject How to generate 'unique' identifiers for use in Cassandra
Date Mon, 26 Apr 2010 20:30:31 GMT
Typically, in the SQL world we use things like AUTO_INCREMENT columns that
let us create a unique key automatically if a row is inserted into a table.

What do you guys usually do to create identifiers for use in Cassandra?

Do we only rely on "currentTimeMills() + random()" to create something that
is 'unique enough' (but theoretically not fail-safe)? Or are some people
here using systems like ZooKeeper for this purpose?
