Active Replication Fabric



eXtremeDB Active Replication Fabric solves 4 challenges for IoT system developers:

1. Bidirectional Replication
2. Intermittent connections
3. Security
4. Compression to maximize low bandwidth networks


Edge nodes’ physical connectivity can be intermittent, and constrained. Some popular protocols have limited bandwidth (ZigBee, NFC and RFID, LPWAN, Low Energy Bluetooth, etc.) and edge device connectivity can be intermittent because of the physical device location (e.g. a mobile device) or because the device is battery operated and connects at certain predefined times. From the standpoint of data management, the unpredictable connectivity means that fully integrated support for “push” and “pull” protocols is important to preserve data collected at the edge.

We use the term “storage containers” for databases maintained on edge devices that are mapped to an upstream database. This defines the replication fabric.

The eXtremeDB Active Replication Fabric APIs allow device-based applications to collect data, then transmit the collected data to servers when connected; likewise they allow replicating server-side data to IoT devices, usually for new device configuration and provisioning.  This data flow is fully automated through the Active Replication Fabric.  The APIs provide automatic or on-demand data exchange between collection points and servers.

XtremeDB Security Features

eXtremeDB security features include Secure Sockets Layer (SSL) connections, a standard security technology that creates an encrypted link between two endpoints, as well as RC4 encryption to secure data at rest, and Cyclic Redundancy Check (CRC) on the database page level to detect unauthorized modifications.


eXtremeDB Data Compression

Run-length encoding (RLE) compression can be applied to columnar data (i.e. fields defined as the ‘sequence’ data type). In McObject’s tests, activating this feature reduced storage space requirements by 75% and increased speed in reading the database by 21%.  eXtremeDB also includes a feature for compressing non-columnar data.
