 Sumo ingests individual metric data points from your metric sources. In metric visualizations, rather than charting individual data points, Sumo presents the aggregated value of the data points received during an interval.
 
-Quantization is the process of aggregating metric data points for time series over an interval, for example, an hour or a minute, using a particular aggregation function: `avg`, `min`, `max`, `sum`, or `count`.

 We use the term rollup to refer to the aggregation function Sumo uses when quantizing metrics. This table describes the different rollup types you can select when running a query.

 Sumo quantizes metrics upon ingestion and at query time.
 
 ### Quantization at ingestion
 
-Upon ingestion, Sumo quantizes raw metric data points to one hour resolutions for all rollup types: `avg`, `min`, `max`, `sum`, and `count`. This data is stored in one hour rollup tables in Sumo. The raw data is stored in a table referred to as the baseline table. For information about retention times, see [Metric Ingestion and Storage](/docs/metrics/manage-metric-volume/metric-ingestion-and-storage.md).
