How does dynomite handle rehashing? #733

Open fengchangfight opened 5 years ago

fengchangfight commented 5 years ago

for example there are previously 3 servers in a single rack, now I'm doing linear scalabiliy, scale UP, make it 6 server in this rack, I guess there must be some data migration happen from the previous 3 servers to the newly added server right? even could be very little keys, since consistent hashing is not perfect. So how does dynomite handle this case by design?

@fabiokung Quick Question, How clients will hit to DynomiteDB? like we have 2 racks in each DC

DC- Rack1 - 3 nodes DC - Rack2 - 3 nodes

like there is any HAPROXY setup in front of this racks? can you share with me the step by step config for this Haproxy or Dyno setup?
