Databases
Streaming SQL engine built on ClickHouse internals, shipping as one small binary

The short version
- Each has a real cost: Couchbase the free tier is a single node with 8 GB of storage and forum support only; Timeplus proton, the free version, is single-node by design, so any requirement for high availability or horizontal scale forces the commercial licence; the open source edition is a trial in practical terms.
- They diverge on capability: Couchbase covers JSON Document Model, Timeplus covers Streaming SQL.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Couchbase
- The free tier is a single node with 8 GB of storage and forum support only
- Node rates are hourly and quoted as starting figures, from $0.15 an hour on Basic to $0.49 on Enterprise
- The Developer Pro and Enterprise plans require 3 nodes, so the hourly rate multiplies before any usage
- Backup storage is billed separately at $0.07 per GB a month, and analytics backups at $0.14
- Support response time is a plan feature, at 8 hours on Developer Pro against 30 minutes on Enterprise
- AI and analytics run as separately priced planes at up to $0.86 an hour per node
Timeplus
- Proton, the free version, is single-node by design, so any requirement for high availability or horizontal scale forces the commercial licence; the open source edition is a trial in practical terms.
- It is a young project against Apache Flink’s decade of production history, so the hiring pool, the connector library and the body of known failure modes are all much smaller.
- Inheriting ClickHouse internals also inherits ClickHouse constraints: memory-hungry queries, awkward updates and a SQL dialect that is not portable to other engines.
- Exactly-once semantics and state recovery guarantees are less battle-tested than Flink checkpointing, which matters if the pipeline moves money.
- Cloud pricing is by provisioned instance size rather than usage, so a bursty workload pays for peak capacity around the clock or has to be resized by hand.
