You could mount a network volume on all your mesos hosts and make that available to the DB container, so that no matter which host handles that job, your data will persist easily.
- tinco 12y agoWhat would the performance characteristics of that be? What configures the network volume? Isn't configuring and maintaining a network volume comparable to configuring and maintaining a database? Mesos is missing something to deal with persistent storage. From what I've heard all teams that employ Mesos don't actually run their persistant storage clusters in Mesos. Perhaps handy for them, but for me that takes most of the use out of Mesos.
- aabhay 12y agoMesosphere's DNS implementation (https://github.com/mesosphere/mesos-dns https://github.com/mesosphere/mesos-dns) helps address that problem. You can use dns routing to create an internal storage or implement a cache that routes cache misses to an external store.
- googamooga 12y agoMesos-DNS has nothing to do with data persistance on mesos. It is just another implementation of cluster service locator.
