- Uploading files using Java SDK class DataLakeFileClient fails to initiate the ADF trigger.
- Uploading files using Azure Portal initiates the trigger as expected.
- ADF trigger is configured to ignore empty blobs.
- Whenever a file is created using ADLS Gen2 REST API, there are 3 operations called at the backend i.e. CreateFile, AppendFile and FlushFile.
- Microsoft.Storage.BlobCreated event is triggered when a blob is created or replaced. Specifically, this event is triggered when clients use the CreateFile and FlushWithClose operations that are available in the Azure Data Lake Storage Gen2 REST API.
- As CreateFile API created a 0 byte blob, the event will not be triggered.
- You can initiate the trigger by adding FlushWithResponse method with close parameter as true.
boolean close = true;
File file = new File("C:\\Users\\mahmoudsamy\\route.txt");
fileClient.flushWithResponse(file.length(), retainUncomittedData, close, httpHeaders, requestConditions, timeout, contect);
Note: Please make sure to pass the correct parameters when using FlushWithResponse to avoid unexpected results.
