# Bulk Operations
 
### Bulk Read and Bulk Write Records

Catalyst enables you to perform bulk read and bulk write operations on the tables in the Data Store using the CLI or the APIs.

* **Bulk Read Records:** This operation reads large volumes of records from a specific table in the Data Store, and generates a CSV file containing the results of the read operation if the job is successful.
* **Bulk Write Records:** This operation fetches large volumes of records from a CSV file uploaded to a [bucket](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/buckets/name-bucket/) in [Stratus](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/introduction/), bulk writes them to a specific table in the Data Store, and generates a report file containing the details of the job execution.

### Bulk Delete Records

Catalyst enables you to delete records in bulk from a specific table in the Data Store, using an API or as an SDK operation.

The bulk delete operation can delete a maximum of 200 rows in a single API call or an SDK operation.
