Terrastore

Terrastore is a modern document store which provides advanced scalability and elasticity features without sacrificing consistency.

Based on Terracotta

Terrastore is based on Terracotta, so it relies on an industry-proven, fast (and cool) clustering technology.

Ubiquitous

Terrastore is accessed through the universally supported HTTP protocol.

Distributed

Terrastore is a distributed document store: nodes can run and live everywhere on your network.

Elastic

Terrastore is elastic: you can add and remove nodes dynamically to/from your running cluster with no downtime and no changes at all to your configuration.

Scalable at the data layer

Terrastore automatically scales your data: documents are partitioned and distributed among your nodes, with automatic and transparent re-balancing when nodes join and leave.

Scalable at the computational layer

Terrastore automatically scales your computations: query and update operations are distributed to the nodes which actually holds the queried/updated data, minimizing network traffic and spreading computational load.

Consistent

Terrastore provides per-document consistency features: you're guaranteed to always get the latest value of a single document, with read committed isolation for concurrent modifications. More complex consistency/transactional requirements, such as multi-document consistency, are not supported in order to guarantee scalability.

Schemaless

Terrastore provides a collection-based key/value interface managing JSON documents with no pre-defined schema: just create your buckets and put everything you want into.

Terrastore, being based on a rock solid technology such as Terracotta, will focus more and more on advanced features and extensibility. Right now, Terrastore provides support for push-down predicates, range queries and server-side update functions.
