POJO Support - Advanced — GigaSpaces JavaSpaces API Plain Old Java Object support - the POJO. This advanced section deals with the annotations and gs.xml mapping file, ways for troubleshooting, considerations, UID generation and usage as well as frequently used code snippets.
Persistency — GigaSpaces's persistency approach consists of several paradigms for data persistency, according to the application needs. This section gives a basic overview of each paradigm.
External Data Source — External Data Source (EDS) is a space component that provides advanced persistency capabilities for the space architecture.
Transaction Manager — OpenSpaces provides several implementations of Spring's PlatformTransactionManager allowing you to use the GigaSpaces and Jini Transaction Manager.
Local Cache and Local View Components — OpenSpaces allows you to easily configure and use the space local view feature using the LocalViewSpaceFactoryBean component and local cache using LocalCacheSpaceFactoryBean.
SQLQuery — The SQLQuery class is used to query the space using the SQL like syntax.
Optimistic Locking — With optimistic locking, you write your program under the assumption that an update operation has a chance of failing, if your updated object has been changed by someone else since you read it.
Pessimistic Locking — In the pessimistic locking approach, your program must explicitly obtain a lock using transaction on one or more objects before making any changes.
Indexing — Setting implicit indexing, extended indexing, and related options.
Cluster-Aware Operations — Supported and non-supported operations, limitations, and considerations when working with a clustered space.
