# Run Aggregation Pipeline

**Run Aggregation Pipeline** are specific data you get from a database when you ask for exactly what you need using a customised search. It's like getting just the right information from a big pile of data by asking the database specific questions.

### Properties Panel

<table><thead><tr><th width="153">Field</th><th width="477">Description</th><th>Required</th></tr></thead><tbody><tr><td>Node name</td><td><a href="/pages/jJ1qO0Ju8d7VFyPB2Jy3"><mark style="color:blue;"><strong>Checkout Node name</strong></mark></a></td><td>true</td></tr><tr><td>Database collection</td><td>Database collection in which you want to query</td><td>true</td></tr><tr><td>Custom Aggregate Query</td><td>Custom aggregation query that you want to execute on collection above</td><td>true</td></tr></tbody></table>

### Returns

`result` - The result of the aggregation query at runtime. You can access this using Magical Autocomplete (e.g. `$.<node_name>.result`) in any node below this node.
