Parameters:

documents - specifies the collection of JSON-serialized documents to import

isUpsert - indicates whether a document in the supplied collection needs to be overwritten if the id already exists

disableAutomaticIdGeneration - indicates whether the id has to be automatically generated for a document if absent in the supplied collection

maxConcurrencyPerPartitionRange - specifies the maximum degree of concurrency per partition key range (default value is 20 if set to null)

Returns:

an instance of BulkImportResponse

Throws:

com.microsoft.azure.documentdb.DocumentClientException - if any failure happens
