Presto is an open-source distributed SQL query engine that is designed for fast analytical queries. The `LIMIT` clause in Presto is used to restrict the number of rows returned by a query.
When you use the `LIMIT` clause in a Presto query, you can specify the maximum number of rows you want to retrieve from the result set. For example, if you want to retrieve only the first 10 rows from a table, you can use the following syntax:
```
SELECT * FROM table_name LIMIT 10;
```
This query will return a result set containing only the first 10 rows from the `table_name` table. The `LIMIT` clause is commonly used in combination with other clauses, such as `ORDER BY`, to retrieve a specific subset of data from a larger result set based on certain criteria.
Please note that the behavior of the `LIMIT` clause may vary depending on the specific version and configuration of Presto you are using, so it's always a good practice to consult the official documentation or refer to the Presto user community for more accurate and up-to-date information.
