About Terracotta Documentation

This documentation is about Terracotta DSO, an advanced distributed-computing technology aimed at meeting special clustering requirements.

Terracotta products without the overhead and complexity of DSO meet the needs of almost all use cases and clustering requirements. To learn how to migrate from Terracotta DSO to standard Terracotta products, see Migrating From Terracotta DSO. To find documentation on non-DSO (standard) Terracotta products, see Terracotta Documentation. Terracotta release information, such as release notes and platform compatibility, is found in Product Information.

Clustered Data Structure Guide

Clustered data structures in Terracotta are functionally equivalent to their non-clustered counterparts. However, there are some performance differences between the different data structures in a clustered context that are important to understand when designing a system. Some of the performance differences are inherent to the design of the data structure; for example, the very different concurrency characteristics of HashMap v. ConcurrentHashMap that play out slightly differently in a clustered context than they do in a non-clustered context. Other performance differences are the result of point-in-time implementation details in the Terracotta core engine.

This guide is intended to provide you with the information you need to make informed decisions about which data structures to use in which context, how to maximize their efficiency, and how to avoid certain pitfalls.
