This is an arbitrary value you choose to uniquely identify your ETL process.
This should be a fixed value that you never change.
It will be written to the [Expander] column of the [ExpandedFile] table.
Syntax
void etl_set_expander_identifier( uint64_t handle, uint64_t application_id );
Parameters
etl_handle
The handle created by the truxton_etl_create call.
application_id
A unique (usually random) value that permanently identifies your ETL process.
Sample
#include <TruxtonCAPI.h>
void main( void )
{
char file_id[ 65 ];
uint64_t message = 0;
uint64_t app = truxton_etl_create();
truxton_etl_set_application_name( app, "Sample C ETL" );
truxton_etl_set_stage_number( app, 42 );
truxton_etl_set_queue_name( app, "SampleC" );
truxton_etl_set_expander_identifier( app, 0x05FC0BF6A57726A0 );
// Pause here until we get a message from the "SampleC" message queue
message = truxton_etl_get_message( app );
while( message != 0 )
{
// Do something with the message
memset( file_id, 0x00, sizeof( file_id ) );
truxton_message_get_file_id( message, file_id, sizeof( file_id ) );
printf( "Received file id %s\n", file_id );
truxton_message_destroy( message );
// Pause here until we get another message from the "SampleC" message queue
message = truxton_etl_get_message( app );
}
truxton_etl_destroy( app );
}
