Bulk Write Rows

Catalyst enables you to perform bulk write jobs on a specific table present in the Data Store. The bulk write operation can fetch thousands of records from a CSV file uploaded in the File Store and insert them in a specific table.

The table is referred to by its unique table ID that is generated by Catalyst during creation. The column in which the write operation must be performed is referred to by its unique column ID.

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

         const bulkWrite = dataStore.table('sampleTable').bulkJob('write');

// create bulk write job
const bulkWriteJob = await bulkWrite.createJob('file_id', {
 find_by: 'EmpID',
 fk_mapping: [
  {
   local_column: 'EmployeeID',
   reference_column: 'EmpID'
  },
  {
   local_column: 'DepartmentID',
   reference_column: 'DeptID'
  }
 ],
 operation: 'insert'
});

// get bulk write status
await bulkWrite.getStatus(bulkWriteJob.job_id);

// get bulk read result
await bulkWrite.getResult(bulkWriteJob.job_id);
