 Given an [SDS stream](https://w3id.org/sds/specification) and its correspondent stream of members, this processor will write everything into a supported data storage system. So far, it only supports MongoDB instances.
 
-SDS stream updates are stored into MongoDB collections for the LDES server to find this information when serving requests. If a `ldes:timestampPath` property is given as part of the dataset metadata, the storage writer will automatically start up a timestamp fragmentation, based on a B+ Tree strategy.
