Technologies
flespi is not about neverending features and eye-candy interfaces. It’s about technologies.
We invent them. We implement them. We share them with you.
Below are some of the core technologies making up a unique technological blend to power your most daring projects.

PVM: Universal protocol parsing technology
Receiving telematics messages from hundreds of GPS tracker types by multiple manufacturers and
giving them to you in an easily manageable format is the primary goal of the flespi telematics
hub. What PVM does is unscrambles each message according to the protocol specification, applies
universal parameter naming, and saves the message in a JSON format.
The common naming scheme enables aggregate data processing across protocols, while the ubiquitous JSON format makes it straightforward to access the data from any target application. The same is true for the opposite direction - you can send commands to devices and they will automatically convert into the proper format for the receiving device.

MDB: Specialized telematics storage
MDB architecture accounts for the specifics of the telemetry messages to guarantee fetching
500,000 messages per second in a block mode and 100,000 messages per second in a random access
mode.
Redundancy mechanisms ensure superior data integrity by replicating data on several database
nodes to deliver RAID-10-like performance.
Once your data gets into the flespi platform, you can rest assured that it’s sitting in a safe place and is available in an instant from anywhere in the world.

HASD: The new generation of hierarchical state database
Inspired by the databases of the 60s but wired using the cutting-edge MQTT 5.0 protocol, HASD
uses retained messages to store data inside flespi MQTT Broker.
The hierarchy is determined by the MQTT topic structure, asynchrony is inherited from the nature of MQTT protocol, object state updates happen automatically via the established subscription.
