Intro to Cortex

A Horizontally Scalable Long-Term Store for Prometheus Chris Marchbanks from Splunk, Kubernetes Colorado October 9, 2019

Cortex

The problem Cortex is solving: with Prometheus, it is hard to query and alert across clusters.

• Cortex is a global store that is long-term and durable

Ingest

• Prometheus sends data to a distributor
• The distributor de-duplicates data
• Sends the data to multiple ingesters
• The ingesters compresses the data in memory, and once it is full will send the data to a long-term store

Query

• ?
