Time Series Databases to Watch

I would love to use Clickhouse, if only it has some kind of Cassandra-esque node-to-node replication mechanism. I'm loathe to bring in something heavy like Zookeeper for that.

It would also be ideal if they could accelerate the data ingestion process somehow without the need to buffer chunks with yet another moving piece like Kafka.

I guess ideally, I'm looking for some kind of standalone HTAP system minus transactional guarantees.

Clickhouse cluster can run without Zookeeper and without replication. Data durability may be provided by using durable storage such as Google Compute Engine disks [1].

Data ingestion process may be accelerated without resorting to Kafka - just insert data into Buffer table [2].
