Very slow db migration to cluster
Not a real bug, maybe.
I trying to migrate 100Gb mysql db to SG cluster. Used many tools for convert\replication - no one succeed. Also can't move PG db to cluster with things like pg_dump.
Every time i got disconects (sometimes at 10Gb, or 50Gb converted) or super slow perfomance - fast at begining, then proccess drasticaly slow down - +20Mb db size per minute.
But no problems to do same migration to usual VM. It takes about 6 hours.
According to benchmarks, cluster performance ~3500tps. should be enough for this.
Any advise with that?
