Method Details

init

@PostConstruct
protected void init()

getDataSource

public ZeebeDataSourceDto getDataSource()

Specified by:

getDataSource in interface ZeebeImportIndexHandler<PositionBasedImportPage,PositionBasedImportIndexDto>

getNextPage

public PositionBasedImportPage getNextPage()

Description copied from interface: ImportIndexHandler

Retrieves all information of the next page to import.

Specified by:

getNextPage in interface ImportIndexHandler<PositionBasedImportPage,PositionBasedImportIndexDto>

getIndexStateDto

public PositionBasedImportIndexDto getIndexStateDto()

Description copied from interface: ImportIndexHandler

Creates a data transfer object (DTO) of the current index state. On every restart of Optimize this information can be used to continue the import where it stopped the last time.

Specified by:

getIndexStateDto in interface ImportIndexHandler<PositionBasedImportPage,PositionBasedImportIndexDto>

resetImportIndex

public void resetImportIndex()

Description copied from interface: ImportIndexHandler

Resets the import index such that it can start the import all over again. E.g., that can be helpful to import entities that were missed during the first round.

Specified by:

resetImportIndex in interface ImportIndexHandler<PositionBasedImportPage,PositionBasedImportIndexDto>

getDatabaseDocID

protected abstract String getDatabaseDocID()

States the database document name where the index information should be stored.
