EventQL vs Vespa: What are the differences?
Developers describe EventQL as "The database for large-scale event analytics". EventQL is a distributed, column-oriented database built for large-scale event collection and analytics. It runs super-fast SQL and MapReduce queries. On the other hand, Vespa is detailed as "Store, search, rank and organize big data". Vespa is an engine for low-latency computation over large data sets. It stores and indexes your data such that queries, selection and processing over the data can be performed at serving time.
EventQL and Vespa can be primarily classified as "Big Data" tools.
EventQL and Vespa are both open source tools. It seems that Vespa with 2.85K GitHub stars and 339 forks on GitHub has more adoption than EventQL with 1.02K GitHub stars and 91 GitHub forks.
