 # Understand labels

+Labels are key-value pairs and can be defined as anything! We like to refer to them as metadata to describe a log stream. If you are familiar with Prometheus, there are a few labels you are used to seeing like `job` and `instance`, and I will use those in the coming examples.
 
 The scrape configs we provide with Grafana Loki define these labels, too. If you are using Prometheus, having consistent labels between Loki and Prometheus is one of Loki's superpowers, making it incredibly [easy to correlate your application metrics with your log data](/blog/2019/05/06/how-loki-correlates-metrics-and-logs--and-saves-you-money/).

 For Loki to be efficient and cost-effective, we have to use labels responsibly. The next section will explore this in more detail.

+Any additional log lines that match those combinations of labels/values would be added to the existing stream. If another unique combination of labels comes in (for example, `status_code="500"`) another new stream is created.
 
 Imagine now if you set a label for `ip`. Not only does every request from a user become a unique stream. Every request with a different action or status_code from the same user will get its own stream.
 
 Doing some quick math, if there are maybe four common actions (GET, PUT, POST, DELETE) and maybe four common status codes (although there could be more than four!), this would be 16 streams and 16 separate chunks. Now multiply this by every user if we use a label for `ip`.  You can quickly have thousands or tens of thousands of streams.

+This is high cardinality, and it can lead to significant performance degradation.
 
 When we talk about _cardinality_ we are referring to the combination of labels and values and the number of streams they create. High cardinality is using labels with a large range of possible values, such as `ip`, **or** combining many labels, even if they have a small and finite set of values, such as using `status_code` and `action`.

 Behind the scenes, Loki will break up that query into smaller pieces (shards), and open up each chunk for the streams matched by the labels and start looking for this IP address.
 
-The size of those shards and the amount of parallelization is configurable and based on the resources you provision. If you want to, you can configure the shard interval down to 5m, deploy 20 queriers, and process gigabytes of logs in seconds. Or you can go crazy and provision 200 queriers and process terabytes of logs!

 This trade-off of smaller index and parallel brute force querying vs. a larger/faster full-text index is what allows Loki to save on costs versus other systems. The cost and complexity of operating a large index is high and is typically fixed -- you pay for it 24 hours a day if you are querying it or not.
