# Bulk Read Rows

Catalyst allows you to perform bulk read jobs on a specific table present in the [Data Store](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-store/introduction). 

In the SDK snippet below, the Bulk Read job can read thousands of records from a specific table and generate a CSV file containing the results of the read operation, if the job is successful. The table is referred to by its unique [Table ID](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-store/tables/).

Catalyst supports the following methods for bulk write in Java SDK:

<table class="content-table">
	<thead>
		<tr>
			<th>Method Used</th>
			<th>Description</th>
		</tr>
	</thead>
	<tbody>
		<tr>
			<td>`createBulkReadJob()`</td>
			<td>Create a new bulk read job.</td>
		</tr>
      <td>`getBulkReadJobStatus()`</td>
      <td>to find out the status and the result of the bulk read job.</td>
    </tr>
	</tbody>
</table>

Copy the SDK snippet below to perform a bulk read job on a particular table.

#### Sample Code Snippet 

**Package Imports**

```java
import com.zc.component.object.bulk.ZCBulkReadServices;
import com.zc.component.object.bulk.ZCBulkQueryDetails;
import com.zc.component.object.bulk.ZCBulkCallbackDetails;
import com.zc.component.object.bulk.ZCDataStoreBulk;
import com.zc.component.object.bulk.result.ZCBulkResult;
import com.zc.component.object.bulk.ZCBulkReadDetails;
```

```java
ZCBulkReadServices bulkRead = ZCDataStoreBulk.getInstance().getBulkReadInstance();
bulkRead.createBulkReadJob(12096000000642178L);  //Provide your Table ID
// create bulkread job with table ID
ZCBulkQueryDetails bulkQueryDetails = ZCBulkQueryDetails.getInstance(); 
// get bulk query details instance
ZCBulkCallbackDetails callbackDetails = ZCBulkCallbackDetails.getInstance(); 
// get bulk callback details instance
bulkRead.createBulkReadJob(12096000000642178L, bulkQueryDetails); //Provide your Table ID
// create bulkread job with table ID and query details
bulkRead.createBulkReadJob(12096000000642178L, bulkQueryDetails, callbackDetails); //Provide your Table ID
// create bulkread job with table ID, query details and callback details.
ZCBulkReadDetails bulkReadDetails = ZCBulkReadDetails.getInstance(); 
// create bulk read details instance.
bulkReadDetails.setTableIdentifier(12096000000642178L); //Provide your Table ID
ZCBulkResult readJob =  bulkRead.createBulkReadJob(bulkReadDetails); 
// create bulkread job with bulk read details.
bulkRead.getBulkReadJobStatus(readJob.getJobId()); 
// get bulk read job status and result

```

> **Note:** A maximum of **200,000 rows** can be read simultaneously using the `createBulkReadJob()` method.
