@avibryant yeah. I don't think that is possible. PMC actually allows merging (compering the bitmaps with and and-or). There is a paper ...

@seiflotfy ah so DPC seems a bit like vHLL - really it's for counting distinct elements per flow.2 replies 0 retweets 0 likes -

@avibryant It focuses on the flow sizes ==> makes it cardinality oriented. If sizes are random then results should be similar to PMC. Right?1 reply 0 retweets 0 likes -

@seiflotfy instead of random numbers they use a hash of the header + first 12 bytes of the content of packet.1 reply 0 retweets 0 likes -

@seiflotfy so if you see the same packet two different places, then later merge the sketches, it only gets counted once (vs twice with PMC).1 reply 0 retweets 0 likes -

@avibryant haven't completed reading the paper yet. But that sounds very right :D On another note I am confused on why no1 picked up PMC yet1 reply 0 retweets 0 likes -

@seiflotfy yeah very surprising, given how well-known HLL and CMS have become. I'm looking forward to doing PMC in Scala when I get time.2 replies 0 retweets 0 likes -

@avibryant fair enough. I found it useful for small cardinalities that require updating, ID change: guest user has become a registered user0 replies 0 retweets 0 likesThanks. Twitter will use this to make your timeline better. UndoUndo
