Issue #2892 has been updated by Daniel Pittman. Status changed from Accepted to In Topic Branch Pending Review Target version changed from 3.x to 2.7.x Branch changed from tickets/master/2892 to https://github.com/puppetlabs/puppet/pull/906
https://github.com/puppetlabs/puppet/pull/906 implements a JSON terminus, which can be configured as the cache terminus in favour of YAML. In my testing it is approximately three times as fast, and I expect the difference to be larger for users with bigger or more complex catalogs. ---------------------------------------- Bug #2892: Improve performance when caching catalog in puppet agent. https://projects.puppetlabs.com/issues/2892#change-66378 Author: Brice Figureau Status: In Topic Branch Pending Review Priority: Normal Assignee: Daniel Pittman Category: plumbing Target version: 2.7.x Affected Puppet version: 0.25.1 Keywords: pson json catalog cache serialization Branch: https://github.com/puppetlabs/puppet/pull/906 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. One possible 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 This has been regularly observed in the field as being a significant performance cost, especially when performing interactive Puppet runs to debug issues interactively. -- You have received this notification because you have either subscribed to it, or are involved in it.
