# What Is CrateDB?
|
|
|
|
[CrateDB](http://github.com/crate/crate) is a distributed SQL database that makes it simple to store and analyze massive amounts of machine data in real-time.
|
|
|
|
Features of CrateDB:
|
|
|
|
- Standard SQL plus dynamic schemas, queryable objects, geospatial features, time series data, first-class BLOB support, and realtime full-text search.
|
|
- 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.
|
|
- CrateDB offers the scalability and flexibility typically associated with a NoSQL database and is designed to run on inexpensive commodity servers and can be deployed and run across 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. And this data can be queried, ad-hoc, in parallel across the whole cluster in real time.

## 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](https://lwn.net/Articles/628829/) that is fixed in kernel versions >= 4.0.
