Ignite Baseline Topology or BLT represents a set of server nodes in the cluster that persists data on disk. Where, N1-2 and N5 server nodes are the member of the Ignite clusters with native persistence which enable data to persist on disk. N3-4 and N6 server nodes are the member of the Ignite cluster but not a part of the baseline topology. The nodes from the baseline topology are a regular server node, that store's data in memory and on the disk, and also participates in computing tasks. Ignite clusters can have different nodes that are not a part of the baseline topology such as: Server nodes that are not used Ignite native persistence to persist data on disk. Usually, they store data in memory or persists data to a 3rd party database or NoSQL. In the above equitation, node N3 or N4 might be one of them. Client nodes that are not stored shared data. To better understand the baseline topology concept, let’s start at the beginning and try to understand its goal and what ...
