This is a MongoDB version of the data connector for the distributed data storage.
To cater for various usage scenarios, the connector can be initialised in two modes based on the values of
the failOnConnectionError parameter:
- false - if the connector fails to connect on start up, it will silently swallow the exception and set the connector to
the
inactivemode. This means all queries for storing interactions will be ignored. This is the default behaviour and should be used when the main role of the connector is to capture interactions. - true - if the connector fails to connect on start up, it will throw an exception preventing the startup of the
application.
This is a useful mode for applications that rely on the connector for their critical functionality, eg.
the
lsd-dostributed-generator-ui.
The following properties can be overridden by setting a System property.
| Property Name | Default | Description |
|---|---|---|
| lsd.dist.db.trustStoreLocation | empty | Useful for connecting to a db instance requiring a certificate of the signing authority (only required for TLS where the certificate is provided). |
| lsd.dist.db.trustStorePassword | empty | Useful for connecting to a db instance requiring a certificate of the signing authority. |
| lsd.dist.db.connectionTimeout.millis | 500 | This value should be higher than the default (the MongoDB driver's default is 20,000) when failOnConnectionError=false. |
| lsd.dist.db.collectionSizeLimit.megabytes | 10,000 | The connector creates the LSD collection as a capped size collection when it's missing with some predefined settings, eg. required indexes, capped size. This values sets the capped size. |
| lsd.dist.db.failOnConnectionError | false | See Modes for details. |
