Re: [Kea-users] HA based on galera

In our case, our MySQL server is basically DBaaS. There was a Meetup presentation about it (https://www.meetup.com/la-mysql/events/228737163/). If you want, I can try to track it down -- the actual MySQL step isn't something I had to engineer myself -- so I was able to take HA for granted. In our

Re: [Kea-users] HA based on galera

Hey Klaus, Can you elaborate a bit on your design? I am in the middle of testing Kea 1.3 with a 3 node mysql setup, and have not seen any issues yet. I researched both MySQL-Cluster and MySQL Group Replication in MySQL5.7. I settled on first testing with group replication, since it did not

Re: [Kea-users] HA based on galera

Re: [Kea-users] HA based on galera

Hi, it might help if you pick a dedicated galera write node, i.e. both of your kea servers write to the same galera node at each point in time. You can still configure that in a HA fashion by some active-passive loadbalancer or a failover IP or something. The other option would be that the kea
