Seems to me like their Channel Servers pretty much does the work of what Cassandra would do, with Consistent Hashing and their Consistent Hash Ring Managers, although it's not detailed how the Channel Servers persist their data and if like Cassandra, they have replication to N Channel Servers. Looks like a specialized variant of how Cassandra works for their use-case, possibly without all the drawbacks of the underlying data structure Cassandra uses for persistence (SSTables), like needing exact ordering of clustering keys when performing queries or dealing with tombstones.

I could see these Channel Servers using something like SQLite for persistence, which would allow the full suite of SQL features without any of the drawbacks of CQL, of which there are many.

The blog post felt a bit high-level and lacking some technical/architectural details that would've given more insight, but nonetheless it was an interesting read!

Something along like this came to my mind but was unable to put it into words! Good you got it.
