Bulk Insert: How to work with bulk insert operation?

One of the features that is particularly useful when inserting large amount of data is bulk inserting. This is an optimized time-saving approach with few drawbacks that will be described later.

Syntax

public BulkInsertOperation bulkInsert();

public BulkInsertOperation bulkInsert(String database);

public BulkInsertOperation bulkInsert(String database, BulkInsertOptions options);

Limitations

There are several limitations to the API:

• Entity Id must be provided at the client side. The client by default will use the HiLo generator in order to generate the Id.
• Transactions are per batch, not per operation and DTC transactions are not supported.
• Documents inserted using bulk-insert will not raise notifications. More about Changes API can be found here.
• Document Updates and Reference Checking must be explicitly turned on (see BulkInsertOptions).
• AfterCommit method in Put Triggers will be not executed in contrast to AllowPut, AfterPut and OnPut.
• The default configuration of the bulk insert is not thread safe, ChunkedBulkInsertOptions inside BulkInsertOptions should be set to null in order to support multi threaded usage. Refer to BulkInsertOptions for more details

Example

try (BulkInsertOperation bulkInsert = store.bulkInsert()) {
  for (int i = 0; i < 1000 * 1000; i++){
    Employee employee = new Employee();
    employee.setFirstName("FirstName #" + i);
    employee.setLastName("LastName #" + i);
    bulkInsert.store(employee);
  }
}
