#### Description:

High Cardinality often becomes a limiting factor in an organization's monitoring journey. The choices that face SREs include dropping labels and relabeling or removing instrumentation to control cardinality spikes. But [Last9](https://last9.io/) - our managed time series data warehouse, provides an alternate option - Streaming Aggregation!

Join us to learn how to manage [high cardinality](https://last9.io/guides/high-cardinality/) with streaming aggregations in real time instead of going back and asking developers to change instrumentation.
