Subject Rebuilding with vnodes
Date Wed, 02 Nov 2016 19:59:29 GMT

I am trying to rebuild a new Data Center with 50 Nodes, and expect 1 TB / node. Nodes are
backed by SSDs, and the rebuild is happening from another DC in same physical region. This
is with 2.1.13.

I am doing this with stream_throughput=200 MB, concurrent_compactors=256, compactionthroughput=0,
and memtable_cleanup_threshold=0.7. (memtable setting was necessary to keep # SSTable files
in check) and running rebuild 20 nodes at a time.

Have people generally attempted to do such large rebuilds ? Any tips ?

Thanks !
