Hi, Aaron

Just sum of total volume for all streams between nodes.

But seems I understand what happened: after repair my column family pass over several minor compactions, and during these compactions it create new tombstones (my CF contain data with TTL, so it can discover and mark new data each time it make minor compaction). As these tombstones arranged and created differently on each node (sstables have different sizes and so on, so size-tiered compaction works slightly different) - each subsequent repair discover new ranges to sync.

When I try to run *major* compaction, and then run repair it vent in minutes (against hours) as far as I understand - because after major compaction tombstones on all nodes are almost the same.

Does it sounds reasonable?

I'll try to find best strategy to minimize repair streams as I'm afraid of major compactions for other, possible large, CFs.

What measure are you using ?

Do you suggest major compaction after repair? I'd like to avoid it.

Repairs generate new files that then need to be compacted.
Maybe that's where the temporary extra volume comes from?

    I can't understand the repair behavior in my case. I have 12

    I have single keyspace 'meter' and two column families (one
    'ids' is small, and second is bigger). The strange thing
    happened today when I try to run
    "nodetool -h 10.254.180.2 -pr meter ids"
    two times one after another. First repair finished successfully

     INFO 16:33:02,492 [repair
    #db582370-8bba-11e1-0000-5b777f708bff] ids is fully synced
     INFO 16:33:02,526 [repair
    #db582370-8bba-11e1-0000-5b777f708bff] session completed
    successfully

    after moving near 50G of data, and I started second session one
    hour later:

    INFO 17:44:37,842 [repair #aa415d00-8bd9-11e1-0000-5b777f708bff]
    new session: will sync localhost/1
    0.254.180.2, /10.254.221.2 <http://10.254.221.2/>, /10.254.191.2
    <http://10.254.191.2/>, /10.254.217.2 <http://10.254.217.2/>,
    /10.253.5.2 <http://10.253.5.2/>, /10.254.94.2
    <http://10.254.94.2/> on range (5,8507
    0591730234615865843651857942052863] for meter.[ids]

    What is strange - when streams for the second repair starts they
    have the same or even bigger total volume, and I expected that
    second run will move less data (or even no data at all).

    Is it OK? Or should I fix something?

    Thanks!
