DeepDB

DeepDB provides simultaneous transactions and analytics (row store and column store)—in the same data set, in
real-time. Official website : http://deep.is/

It claims to be fully transactional (ACID compliant) and introduces breakthroughs covering six fundamental attributes to the performance:

 

Constant-Time Indexing

Minimizes indexing cost, enabling highly
indexed databases

Updates indexes in real-time, in-memory 
and on disk

Uses summary indexing to achieve
yottabyte scale

Segmented Column Store

Adds columnar attributes to table-
oriented indexes

Embeds meta-data including
statistical aggregation

Allows for delta updates instead
of a full column rebuild

 

Streaming I/O

Massively optimized, enabling wire-
speed throughput

Concurrent operations for updates 
in-memory and on-disk

Optimizations for SSD, HDD, and 
in-memory-only operation

 

Intelligent Caching

Eliminates on-disk tree traversals

Adaptive segment sizes (no fixed pages)

Point-read capable,
retrieves only what is necessary

 

Adaptive Concurrency

Minimizes delays and wait states to maximize
CPU throughput

Fine-grained lightweight
locking mechanisms

Eliminates most OS context switches

 

Designed for the Cloud

Continually optimizing system

Eliminates downtime for
scheduled maintenance

Zero-touch adaptive configuration
