Bulk Read Rows

Catalyst allows you to perform bulk read jobs on a specific table present in the Data Store.

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. The datastore_service reference used below is already defined in the component instance page.

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

bulk_read = datastore_service.table("sampleTable").bulk_read()
# create bulk read job

// Get bulk read status
status = bulk_read.get_status(bulk_read_Job['job_id']) 
// Get bulk read result
result = bulk_read.get_result(bulk_read_Job['job_id'])
