When I restore 4096 LS, 4354 LSP, 256 LR and 256 LRP, (I clean up all DBs before restore.) it takes a few seconds to restore the nb-db. But onv-northd takes forever to update sb-db.
I changed sb-db election timer from 1s to 10s. Then it takes just a few minutes for sb-db to get fully synced. How does that sb-db leader switch affect such sync? Thanks!
