rob05c commented on issue #2199: Add Grove In-Place Upgrades URL: https://github.com/apache/incubator-trafficcontrol/issues/2199#issuecomment-385796941 Idea: serialize memory to disk, and use a disk cache for the time it takes to shut down the old process. So, slightly degraded performance, but only for the minute or so it takes to kill the old app, and then we load the disk back into memory. And we’re still not making more Parent/Origin requests than necessary Also, use a small (say 100mb) memory LRU, for requests for the same asset which was on disk, and for requests to new assets (which, especially for Linear content, all assets will be new after about 5 seconds). That further reduces the performance degradation.
