# Stream onchain data with Mirror

Mirror streams **onchain data directly to your database**, with \<1s latency.

Using a database offers unlimited queries and the flexibility to easily combine onchain and offchain data together in one place.

      You can [source](/mirror/sources/supported-sources) the data you want via
      a subgraph or direct indexing, then use
      [transforms](/mirror/transforms/transforms-overview) to further filter or
      map that data.

      Mirror can minimize your latency if you're [running an
      app](/mirror/sinks/supported-sinks#for-apis-for-apps), or maximize your
      efficiency if you're [calculating analytics](/mirror/sinks/supported-sinks#for-analytics).

Behind the scenes, Mirror automatically creates and runs data pipelines for you off a `.yaml` config file. Pipelines:

1. Are reorg-aware and update your datastores with the latest information
2. Fully manage backfills + edge streaming so you can focus on your product
3. Benefit from quality checks and automated fixes & improvements
4. Work with data across chains, harmonizing timestamps, etc. automatically

Set up your first database by [creating a pipeline](/mirror/create-a-pipeline) in 5 minutes.
