== Rolling up historical data
|
|
|
|
experimental[]
|
|
|
|
NOTE: For version 8.5 and above we recommend <<downsampling,downsampling>> over
|
|
rollups as a way to reduce your storage costs for time series data.
|
|
|
|
Keeping historical data around for analysis is extremely useful but often avoided due to the financial cost of
|
|
archiving massive amounts of data. Retention periods are thus driven by financial realities rather than by the
|
|
usefulness of extensive historical data.

// tag::rollup-intro[]
|
|
The {stack} {rollup-features} provide a means to summarize and store historical
|
|
data so that it can still be used for analysis, but at a fraction of the storage
|
|
cost of raw data.
