Issue #2892 has been updated by Markus Roberts. Status changed from Code Insufficient to Rejected Priority changed from High to Normal Target version changed from Rowlf to Statler
The new yaml encoding and the PSON encoding are both significantly more efficient in speed and memory usage than the yaml library in use when this ticket was filed. Testing this afternoon I was seeing a ~5x to ~15x speed improvement and a ~60% memory reduction. This reduces the potential benefit of re-using the transmitted format. Given that and some of the problems behind the idea (e.g., that network-serialization isn't always yaml, it could, for example, be pson or even marshall) I'm closing this ticket in favor of #3714. ---------------------------------------- Bug #2892: Remove unneeded YAML serialization when caching catalog in puppetd http://projects.puppetlabs.com/issues/2892 Author: Brice Figureau Status: Rejected Priority: Normal Assigned to: Markus Roberts Category: plumbing Target version: Statler Affected version: 0.25.1 Keywords: pson json catalog cache serialization Branch: tickets/master/2892 Peter Meier noticed that the puppetd catalog caching was an operation that was taking lots of RAM. Analysis show that for large catalog YAML dumping consumes lots of memory (roughly 3x times the object to serialize). The catalog is sent from the master to the client in serialized format (usually pson/json), the idea would be to directly use it as the local client cache, instead of re-serializing the "live" catalog. The implementation would be: # keep the serialized version of the catalog in the request in the REST client # when caching the catalog, have a specific terminus that would just dump this string to disk -- You have received this notification because you have either subscribed to it, or are involved in it.
