Hey Guys,
I'm working on a project and one of the requirements is to have a schema free
CF where end users can insert arbitrary key/value pairs per row. What would be
the best way to know what are all the "keys" that were inserted (preferably w/o
any locking). For example,
Row1 => key1 -> XXX, key2 -> XXX
Row2 => key1 -> XXX, key3 -> XXX
Row3 => key4 -> XXX, key5 -> XXX
Row4 => key2 -> XXX, key5 -> XXX
…
The query would be give me all the inserted keys and the response would be
{key1, key2, key3, key4, key5}
Thanks,
Drew
