Method Detail

createProcess

public String createProcess(String resourceIngestionDefinitionId,
                            String ingestionConfigurationId,
                            String type,
                            String status,
                            Variant metadata)

Description copied from interface: IngestionProcessRepository

Creates a new ingestion process.

Specified by:

createProcess in interface IngestionProcessRepository

Parameters:

resourceIngestionDefinitionId - resource ingestion definition id

ingestionConfigurationId - ingestion configuration id

type - process type

status - initial process status

metadata - process metadata

Returns:

id of the created process

updateStatus

public void updateStatus(String processId,
                         String status)

Updates the status of an ingestion process with the specified id. This implementation assumes that process cannot be in FINISHED status and finished_at timestamp must be null to perform the update.

Specified by:

updateStatus in interface IngestionProcessRepository

Parameters:

processId - process id

status - new process status

Throws:

IngestionProcessUpdateException - if no rows were updated or more than 1 row was updated

updateStatus

public void updateStatus(String resourceIngestionDefinitionId,
                         String ingestionConfigurationId,
                         String type,
                         String status)

Updates the status of an ingestion process with the specified resource ingestion definition id, ingestion configuration, and process type.

This update method is not recommended, as technically multiple processes can fit the specified criteria. It should only be used when the status update is a part of a resource update. This implementation assumes that process cannot be in FINISHED status and finished_at timestamp must be null to perform the update.

Specified by:

updateStatus in interface IngestionProcessRepository

Parameters:

resourceIngestionDefinitionId - resource ingestion definition id

ingestionConfigurationId - ingestion configuration id

type - process type

status - new process status

Throws:

IngestionProcessUpdateException - if no rows were updated

endProcess

public void endProcess(String processId)

Ends an ingestion process with the specified id.

The ending of the process will set the status to a terminal value and update the process' finishedAt timestamp. This implementation assumes that process cannot be in FINISHED status and finished_at timestamp must be null to perform the update.

Specified by:

endProcess in interface IngestionProcessRepository

Parameters:

processId - process id

Throws:

IngestionProcessUpdateException - if no rows were updated or more than 1 row was updated

endProcess

public void endProcess(String resourceIngestionDefinitionId,
                       String ingestionConfigurationId,
                       String type)

Ends an ingestion process with the specified resource ingestion definition id, ingestion configuration, and process type.

This update method is not recommended, as technically multiple processes can fit the specified criteria. It should only be used when the status update is a part of a resource update.

The ending of the process will set the status to a terminal value and update the process' finishedAt timestamp. This implementation assumes that process cannot be in FINISHED status and finished_at timestamp must be null to perform the update.

Specified by:

endProcess in interface IngestionProcessRepository

Parameters:

resourceIngestionDefinitionId - resource ingestion definition id

ingestionConfigurationId - ingestion configuration id

type - process type

Throws:

IngestionProcessUpdateException - if no rows were updated
