`limit`

Description

The limit command restricts the number of documents returned by a query to a specified count. It is typically used after sorting or aggregation operations to retrieve only the most relevant or top results from a larger dataset.

This command is especially useful for performance optimization or for displaying only a subset of high-value results (for example, the top 100 users or the most recent 50 logs).

Note

The limit command does not guarantee order unless used after an explicit orderby. If order matters, always pair it with orderby to ensure predictable results.

Syntax

limit <event-count>

Example

Use case: Show the top 100 users by activity

Suppose you want to analyze the most active users by counting their log activity. After aggregating and sorting by total hits, you can apply limit to return only the top 100 users.

Example data

{ "path": "/home", "user": "chris" },
{ "path": "/home", "user": "dave" },
{ "path": "/home", "user": "maya" },
{ "path": "/checkout", "user": "chris" },
{ "path": "/login", "user": "dave" }
{ "path": "/blog", "user": "chris" },
{ "path": "/about", "user": "Eugene" }

Example query

groupby user count() as hit_count
| orderby hit_count desc
| limit 2

Example output

{ "user": "chris", "hit_count": 3 },
{ "user": "dave", "hit_count": 2 }

The limit command truncates the result set to the first 100 users based on the ordering applied. Since there are only 3 users in this example, all are returned.

Tip

You can achieve similar behavior with the top command, which combines ordering and limiting in one operation.
