Quick questions on upgrading Flink. All our jobs are compiled against Flink 1.8.x
We are planning to upgrade to 1.10.x 1. Is the recommended path to upgrade one minor at a time, i.e. 1.8.x -> 1.9.x and then 1.9.x -> 1.10.x as a second step or is the big jump supported, i.e. 1.8.x -> 1.10.x in one change 2. Do we need to recompile the jobs against the newer Flink version before upgrading? Coordinating multiple teams can be tricky, so - short of spinning up a second flink cluster - our continuous deployment infrastructure will try to deploy the topologies compiled against 1.8.x for an hour or two after we have upgraded the cluster
