XTA - XA Transaction API
XTA is a new API that provides two phase commit feature to applications. In comparison with other existent approaches, XTA has been designed to work in a serverless environment with a FaaS (Function as a Service) model. Moreover, the two phase commit feature is supplied to the applications with a TXaaS (Transaction as a Service) model. Here are the most valuable characteristics:
- Serverless
- Distributed Applications
- Distributed Resources
- Transaction as a Service
- Polyglot
- XA Resource Managers
- non XA Resource Managers
Serverless
Applications do not have to use a specific application server to use XTA. XTA is just a library that must be linked by applications.
Distributed Applications
Any number of different Applications, distributed in different systems, can participate in the same global XA transaction. XTA requires only TCP/IP connectivity.
Distributes Resources
Any number of different Resources like SQL databases, NoSQL databases, messaging brokers, etc… can participate in the same global XA transaction.
Transaction as a Service
XTA uses the LIXA state server to persist transaction state and to synchronize different applications. LIXA state server is accessed by XTA using an XML message oriented, protocol based on standard TCP/IP connection.
Polyglot
Application developed with different programming languages can participate in the same global XA transacation. Currently available languages are: C, C++, Java and Python.
XA Resource Managers
XTA natively recognizes XA standard Resource Managers.
non XA Resource Managers
XTA provides an interface that can be implemented by any Resource Manager that can support two phase commit indipendently from XA standard.
XTA documentation
XTA documentation is available inside the LIXA manual
