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.


Terrastore is accessed through the universally supported HTTP protocol.


Terrastore is a distributed document store supporting single-cluster and multi-cluster deployments.


Terrastore is elastic: you can add and remove nodes dynamically to/from your running cluster(s) 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.


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.


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.
Easy operations
Install a fully working cluster in just a few commands and no XML to edit.

Focused on data management and processing features

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:
  • Custom data partitioning.
  • Event processing.
  • Push-down predicates.
  • Range queries.
  • Map/Reduce querying and processing.
  • Server-side update functions.
