Is it possible to use bounded-load consistent hashing with stick tables?
I have a case where I want to use bounded-load consistent hashing and I want to have consistency across multiple haproxy nodes. I’m using a DNS resolver to generate my servers by using the server-template, but my DNS resolver returns the IPs in a round-robin order, which causes inconsistency across the haproxy nodes. Example:
haproxy 1:
svr1 → 10.2.174.177
svr2 → 10.2.174.178
haproxy 2:
svr1 → 10.2.174.178
svr2 → 10.2.174.177
Therefore, I wonder if by using stick-tables with srvkey addr (to map my balance key with the server address instead of the server name) would it work? How the hash-balance-factor generates the relation between balance key and server reference?
This is my backend haproxy config:
backend back
mode http
balance url_param id
hash-type consistent
hash-balance-factor 150
stick-table type string size 1m srvkey addr
stick store-request url_param(id) table back
stick on url_param(id) table back
