Introduction

N3uron Historian is a high-performance time-series storage system based on a MongoDB database. In x64 bit systems, the MongoDB instance is automatically installed in the N3uron installation folder, so that Historian is ready to store data as soon as installation is complete. In addition, an external MongoDB database can be used instead of the embedded MongoDB instance. Data can also be stored simultaneously in multiple Historians. In x32 and ARM architectures, the user may first install MongoDB and configure Historian to store data in the external MongoDB instance.

N3uron Historian can store any tag values that have been collected locally in the same node, or those collected remotely by other nodes and received in the Historian node through N3uron Links. It also provides a built-in Store & Forward mechanism that stores data locally in case of communication loss between N3uron and the database.

Historian provides efficient data compression and partitioning mechanisms, allowing for massive volumes of time-series data to be stored without reducing its performance over time. As a reference for disk usage estimation, 1GB of hard drive stores approximately 100 million events (value changes).
