Hi everyone, The hiera command line program (version 0.3.0) is currently taking around 2 seconds per invocation. This seems quite slow to me, but is probably not an issue for most users.
We have a number of legacy machines that for one reason or another have not been puppetised yet, and probably won't be anytime soon, so I have a somewhat clever script that, for each of these hosts, uses the hiera command like utility to export a few puppet-templated documents just as puppet+hiera does for our puppeted server. This works very nicely, but involves ~250 hiera lookups per host, which at 2 seconds per lookup, is taking more than 8 minutes per host (and using near 100% of a CPU core the entire time). As we have ~40 such hosts, that's over 5 hours with no concurrency (we do use some concurrency, but since each invocation uses near 100% of a CPU core each, there's no point running more simultaneous hiera processes than the number of CPUs, and even then, we need some reserved for other services). So, is there some way I can make this export run faster? The bulk of the time seems to be spent in initialising the hiera command line program, not the actual data lookup (for example, if I fail to provide the necessary identity / scope files, it still takes 2 seconds to get around to returning an error, but if I fail to provide a config file, it returns instantaneously with error). So, I'd either like to make the program load / initialise much faster, or be able to query multiple values for a single hiera command line invocation. Also, is there a more recent version of hiera that would be faster? (I'm a little unclear about hiera versioning - we're running 0.3.0, but I don't know if that's recent or old). Any suggestions / tips would be greatly appreciated :) Thanks. Paul. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
