What Is CrateDB?

CrateDB is a distributed SQL database that makes it simple to store and analyze massive amounts of machine data in real-time.

CrateDB offers the scalability and flexibility typically associated with a NoSQL database, is designed to run on inexpensive commodity servers and can be deployed and run on any sort of network - from personal computers to multi-region hybrid clouds.

The smallest CrateDB clusters can easily ingest tens of thousands of records per second. The data can be queried, ad-hoc, in parallel across the whole cluster in real time.

Features

• Standard SQL plus dynamic schemas, queryable objects, geospatial features, time series data, first-class BLOB support, and realtime full-text search. • Dynamic schemas, queryable objects, geospatial features, time series data support, and realtime full-text search providing functionality for handling both relational and document oriented nested data structures. • Horizontally scalable, highly available and fault tolerant clusters that run very well in virtualized and containerised environments. • Extremely fast distributed query execution. • Auto-partitioning, auto-sharding, and auto-replication. • Self-healing and auto-rebalancing.

Issues

Memory Accounting

The combinations of Linux kernel version 3.x and Docker >= 1.12 could lead to a major problem with memory accounting causing the kernel to kill the CrateDB process in the container. This problems occurs because of a slab shrinker issue that is fixed in kernel versions >= 4.0.
