MongoDB-VLS is a prototype implementation of VLS in MongoDB. VLS, or Virtual Lightweight Snapshots, is a mechanism, presented at ICDE 2016, that enables consistent analytics without blocking incoming updates in NoSQL stores.
MongoDB-VLS implementation and experiments are available here.
ReproZip packages for the plots of the ICDE paper are available here.
For instance, to reproduce Figure 7:
$ reprounzip vagrant setup query_execution_time.rpz query_execution_time/
$ reprounzip vagrant run query_execution_time/
$ reprounzip vagrant download query_execution_time/ scan_duration.png
$ reprounzip vagrant download query_execution_time/ scan_duration_updates.png
