Heroic vs ZeroDB: What are the differences?
Heroic: A scalable time series database based on Cassandra and Elasticsearch, by Spotify. Heroic is Spotify's in-house time series database. It was built to address the challenges Spotify was facing with near real-time data collection and presentation at scale; ZeroDB: Moving on-premise databases to the cloud, cheaply and securely. ZeroDB enables clients to run queries over encrypted databases without exposing decrypted data to the server and without a proxy gateway. Data at rest and in use is secure - the cloud is no longer a single point of failure.
Heroic and ZeroDB can be primarily classified as "Databases" tools.
Some of the features offered by Heroic are:
- heroic-core contains the com.spotify.heroic.HeroicCore class which is the central building block for setting up a Heroic instance.
- heroic-elasticsearch-utils is a collection of utilities for interacting with Elasticsearch. This is separate since we have more than one backend that needs to talk with elasticsearch.
- heroic-parser provides an Antlr4 implementation of com.spotify.heroic.grammar.QueryParser, which is used to parse the Heroic DSL.
On the other hand, ZeroDB provides the following key features:
- End-to-End DB Encryption
- Queries Over Encrypted Data
- Direct Cloud Sharing
Heroic and ZeroDB are both open source tools. It seems that ZeroDB with 1.58K GitHub stars and 99 forks on GitHub has more adoption than Heroic with 710 GitHub stars and 89 GitHub forks.
