Julius Volz	6dc36d0c3e	Don't keep extra labels in aggregations by default. MIN/MAX/SUM/AVG/COUNT aggregations will now by default drop all labels that are not specifically part of a BY-clause, even if a label value is the same within all timeseries of an aggregation group. The old behavior of keeping extra labels may still be switched on by adding KEEPING_EXTRA to the end of an aggregation statement: sum(http_requests) by (job, method) keeping_extra I'm open to better syntax/naming suggestions.

Julius Volz	740d448983	Use custom timestamp type for sample timestamps and related code. So far we've been using Go's native time.Time for anything related to sample timestamps. Since the range of time.Time is much bigger than what we need, this has created two problems: - there could be time.Time values which were out of the range/precision of the time type that we persist to disk, therefore causing incorrectly ordered keys. One bug caused by this was: https://github.com/prometheus/prometheus/issues/367 It would be good to use a timestamp type that's more closely aligned with what the underlying storage supports. - sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit Unix timestamp (possibly even a 32-bit one). Since we store samples in large numbers, this seriously affects memory usage. Furthermore, copying/working with the data will be faster if it's smaller. MEMORY USAGE RESULTS Initial memory usage comparisons for a running Prometheus with 1 timeseries and 100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my tests, this advantage for some reason decreased a bit the more samples the timeseries had (to 5-7% for millions of samples). This I can't fully explain, but perhaps garbage collection issues were involved. WHEN TO USE THE NEW TIMESTAMP TYPE The new clientmodel.Timestamp type should be used whenever time calculations are either directly or indirectly related to sample timestamps. For example: - the timestamp of a sample itself - all kinds of watermarks - anything that may become or is compared to a sample timestamp (like the timestamp passed into Target.Scrape()). When to still use time.Time: - for measuring durations/times not related to sample timestamps, like duration telemetry exporting, timers that indicate how frequently to execute some action, etc. NOTE ON OPERATOR OPTIMIZATION TESTS We don't use operator optimization code anymore, but it still lives in the code as dead code. It still has tests, but I couldn't get all of them to pass with the new timestamp format. I commented out the failing cases for now, but we should probably remove the dead code soon. I just didn't want to do that in the same change as this. Change-Id: I821787414b0debe85c9fffaeb57abd453727af0f	11 years ago
Julius Volz	6b7de31a3c	Upgrade to LevelDB 1.14.0 to fix LevelDB bugs.

Conor Hennessy	eba01d1119	Remove usage of gorest. Due to on going issues, we've decided to remove gorest. It started with gorest not being thread-safe (it does introspection to create a new handler which is an easy process to mess up with multiple threads of execution): https://code.google.com/p/gorest/issues/detail?id=15 While the issue has been marked fixed, it looks like the patch has introduced more problems than the original issue and simply doesn't work properly. I'm not sure the behaviour was thought through properly. If a new instance is needed every request then a handler-factory is needed or the library needs to set expectations about how the new objects should interact with their constructor state. While it was tempting to try out another routing library, I think for now it's better to use dumb vanilla Go routing. At least until we decide which URL format we intend to standardize on.
