Whenever I’m thinking about a new company or tech breakthrough, I ask myself how it helps us get to a world that can support a few billion or even a trillion devices.
One obvious challenge is the current cloud computing model, where information and data is centralized and then pushed to devices.
As I talked about a few weeks ago, there isn’t enough room in current or future cloud computing infrastructure to support all of the data generated by connected products.
To solve this problem, Berlin-based startup ObjectBox has created a distributed, low-resource database that can synchronize information from different devices.
ObjectBox can run on devices that don’t have a lot of memory or computing power.
It uses a client-server model of information exchange, with the client devices requiring 1 megabyte of memory to run the database.
Smaller devices, such as sensors, only need about 50 kilobytes of memory, says CEO Vivien Dollinger.
The ObjectBox database memory requirements are incredibly low, which means you can put the database in everything ranging from an Intel-based edge gateway to a temperature sensor running an ARM microcontroller.
When it comes to how it handles synchronization, it’s easier to think of the database as almost a client-server model.
The ObjectBox sync feature only offers synchronization of pre-selected data, as opposed to a true replication of all the data stored in the database.
But it’s enough to handle things like the state of a device without having to request that information from the cloud.
Dollinger says a developer would have to select which data gets synced across all of the devices, and that it’s more of a “pull” model than a “push” model.
That means the smarter versions of the database will pull the information needed from sensors when needed.
Because a device’s state can exist outside of the cloud, it’s possible to envision a group of home or enterprises devices that communicate locally on their own intranet
