TimescaleDB is an open-source database designed to make SQL scalable for time-series data. It is engineered up from PostgreSQL, providing automatic partitioning across time and space (partitioning key), as well as full SQL support. TimescaleDB is packaged as a PostgreSQL extension and released under the Apache 2 open-source license. 
 
TimescaleDB automatically scales and spreads data written to a hypertable into many dynamically-created chunks. Hypertables present the abstraction of a single table, yet transparently partitioned by time and space, they enable high insert rates even at billions of rows.

Kong is a cloud-native, fast, scalable, and distributed Microservice Abstraction Layer (also known as an API Gateway, API Middleware or in some cases Service Mesh). Backed by the battle-tested NGINX with a focus on high performance, Kong was made available as an open-source platform in 2015. Under active development, Kong is used in production at thousands of organizations from startups, Global 5000 and Government organizations.
 
If you are building for web, mobile or IoT (Internet of Things) you will likely end up needing common functionality to run your actual software. Kong can help by acting as a gateway (or a sidecar) for microservices requests while providing load balancing, logging, authentication, rate-limiting and more through plugins.
 
Its features include: 
<ul>
<li>Cloud-Native: Platform agnostic, Kong can run from bare metal to
Kubernetes.</li>
<li>Dynamic Load Balancing: Load balance traffic across multiple backend
services.</li>
<li>Service Discovery: Resolve SRV records in third-party DNS resolvers like
Consul.</li>
<li>Serverless: Invoke and secure AWS Lambda or OpenWhisk fuctions directly
from Kong.</li>
<li>WebSockets: Communicate to your upstream services via WebSockets.</li>
<li>OAuth2.0: Easily add OAuth2.0 authentication to your APIs.</li>
<li>Logging: Log requests and responses to your system over HTTP, TCP, UDP,
or to disk.</li>
<li>Security: ACL, Bot detection, whitelist/blacklist IPs, etc...</li>
<li>Syslog: Logging to System log.</li>
<li>SSL: Setup a Specific SSL Certificate for an underlying service or API.</li>
<li>Monitoring: Live monitoring provides key load and performance server
metrics.</li>
<li>Authentications: HMAC, JWT, Basic, and more.</li>
<li>Rate-limiting: Block and throttle requests based on many variables.</li>
<li>Transformations: Add, remove, or manipulate HTTP requests and responses.</li>
<li>Caching: Cache and serve responses at the proxy layer.</li>
<li>CLI: Control your Kong cluster from the command line.</li>
<li>REST API: Kong can be operated with its RESTful API for maximum
flexibility.</li>
<li>Geo-Replicated: Configs are always up-to-date across different regions.</li>
<li>Failure Detection &amp; Recovery: Kong is unaffected if one of your Cassandra
nodes goes down.</li>
<li>Clustering: All Kong nodes auto-join the cluster keeping their config
updated across nodes.</li>
<li>Scalability: Distributed by nature, Kong scales horizontally by simply
adding nodes.</li>
<li>Performance: Kong handles load with ease by scaling and using NGINX at
the core.</li>
<li>Plugins: Extendable architecture for adding functionality to Kong and
APIs.</li>
</ul>
