* lib/storage: add ability to use downsampling for the given series filter Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * docs: add information about downsampling filters Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * docs: fix MetricsQL filter Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * lib/storage/downsampling: treat missing downsampling filter as a bug Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * lib/storage/part_header: verify correctness of downsampling filters when opening partition Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * lib/storage/downsampling: save only appliable rules in part metadata Filter and save only rules which are appliable to partition based on MinTimestamp of stored data. Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * lib/storage/downsampling: update log messages for final dedup Properly specify a reason of re-running deduplication for partition. Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * lib/storage: consistently use MaxTimestamp to determine deduplication/downsampling rules Using MinTimestamp leads to applying downsampling to parts which are only partially covered by downsampling rule. For example, partition covers range [1000-2000]. At t=2100 and rule offset 500 data with t=2100-500 => 1600 must be downsampled. The range check against MinTimestamp evaluates to true even though partition contains range which must not be downsampled - [1600:2000]. Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * Follow-up - Apply the first matching downsampling period if multiple filters match the given time series. This allows fine-tuning the downsampling config for the specific needs. - Take into account downsampling filters during search queries. - Reduce the difference between community and enterprise branches. This should simplify further maintenance of these branches. - Properly parse series filters with colons inside them. - Document the feature at docs/CHANGELOG.md.
