5% migration of S0 RPC traffic to getlogs
idea of the task is to redirect 5% of our RPC traffic to the offchain getlogs endpoint and measure the impacts it has on our harmony ecosystem
current DNS configuration
api.s0.t.hmny.io and api.harmony.one are currently configured as latency based split into different region/data center
when a region goes down, traffic will be redirected to another region/data center
proposed work
Latency based routing will be updated to CNANEs to the region/DC (not the actual endpoint)
ie : for region : Europe (Frankfurt) eu-fra.api.harmony.one or eu-fra.s0.t.hmny.io
2 weighted (5/95) CNAME pointing to the respective endpoint will then be created
risks and potential issue
the current getlogs endpoints backend is only located in the US AWS DC. 5% of the traffic might be responding slower than usual
