Time-series databases

I want to pick an open-source replacement for Kdb+ (storing readings and events over time, such as sensor data and trades). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - QuestDB: QuestDB is an open-source database built for time-stamped data, such as trades, sensor readings and events, that arrives very fast. It is for engineers and analysts who need to store, query and analyze large streams of time-based data with SQL. [Advanced setup; Windows · Linux; replaces fully; Apache-2.0; https://github.com/questdb/questdb] - InfluxDB: InfluxDB is a database that stores and quickly queries data that arrives over time, such as sensor readings, server metrics and events. It is aimed at developers and operators who build dashboards, monitoring and automation. [Advanced setup; runs on a server you set up; replaces fully; Apache-2.0; https://github.com/influxdata/influxdb] - TDengine: TDengine is an open-source database built to store and analyze very large volumes of time-stamped data from sensors and machines. It is aimed at developers and operators running Internet of Things, connected-car and industrial systems. [Advanced setup; Mac · Linux; replaces fully; AGPL-3.0; https://github.com/taosdata/TDengine] - CrateDB: CrateDB is a database that stores and searches large amounts of data, including time-based readings, and can run across many machines at once. It is aimed at developers and data teams who need fast analysis of data as it arrives. [Advanced setup; runs on a server you set up; replaces fully; Apache-2.0; https://github.com/crate/crate] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/time-series-databases.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/time-series-databases.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
