HarperDBΒΆ

The foglamp-north-harperdb plugin sends data from FogLAMP to the HarperDB database. HarperDB is a geo-distributed database with hybrid SQL & NoSQL functionality in one powerful tool, accessed via a REST API. Each asset that is read by FogLAMP is written to a separate table within the specified HarperDB schema. The plugin will support both local installations and cloud installations of HarperDB.
