   This class is the configuration object that is initialized in auth.datalab.siesta.siesta_main from the command arguments.

   This class is the configuration object that is initialized in auth.datalab.siesta.siesta_main from the command arguments. It holds the following information

   system

   What system will be used for indexing (Signature, Set-Containment, SIESTA or online SIESTA)

   database

   In what database the data will be stored. Note that for Signature and Set-Containment only Cassandra is available. Therefore only for SIESTA both options are available.

   mode

   This parameter is specific for siesta and determines whether the timestamps or positions of the event type pairs will be stored in IndexTable

   filename

   The path to the logfile that will be indexed

   log_name

   The name of the log database. Since multiple log databases can be available (similar to SQL). The same name must be given if this is an incremental indexing, in order to append the log in the correct tables.

   compression

   The compression algorithm that will be used while storing the indices in the database.

   delete_all

   Flag parameter determines if all the previous tables in the database (despite the log database name) will be deleted.

   delete_previous

   Flag parameter determines if the previous tables of this particular log database will be deleted.

   lookback_days

   Numeric parameter, determines the maximum distance (in days) between two events in order to create an event pair. That is if two events' timestamp have difference larger than this parameter they will be not stored in IndexTable.

   traces

   This parameter concerns the random generator. Defines the number of traces that will be random generated.

   event_types

   This parameter concerns the random generator. Defines the number of event types that will be contained in the traces.

   length_min

   This parameter concerns the random generator. Defines the minimum length of the generated traces.

   length_max

   This parameter concerns the random generator. Defines the maximum length of the generated traces.

   k

   Specifies the number of frequent events that will be used in the Signature method. If -1 is set it will use k=|unique event types|

   duration_determination

   Flag parameter determines if the duration of the events will be calculated and stored in.
