FoundationDB has announced the general availability of SQL Layer, and ANSI SQL engine that runs on top of their key-value store. The result is a relational database backed up by a scalable, fault-tolerant, shared-nothing, distributed NoSQL store with support for multi-key ACID transactions.
FoundationDB database platform combines NoSQL scalability with ACID transactions across all data within the database. FoundationDB team announced last month the availability of its new NoSQL database platform.
RavenDB 2.0 was recently released with several new features. In an InfoQ exclusive interview, Oren Eini (Ayende Rahien), founder and project lead of RavenDB, shares the rationale behind various decisions in the project, as well as what’s coming up.
FoundationDB is a database that provides ACID guarantees along with high performance and availability normally associated with NoSQL databases. In an InfoQ exclusive interview, we learn more about the project from one of the founders, Nick Lavezzo.
After several years of development, the developers from NeoTechnology have released version 1.0 of Neo4j, a Java-based graph database which follows the property graph datamodel. InfoQ spoke with NeoTechnology COO Peter Neubauer to learn more about the current Neo4j release and what it offers to developers.
Despite the extreme importance of transaction processing for ensuring reliability and manageability of distributed computing and several existing WS-* standards, the implementation of the transactional behavior in SOA is still pretty rare. The Reservation pattern, described in a new post by Arnon Rotem-Gal-Oz, provides one of the possible solutions to this problem.
In this interview from QCon San Francisco 2007, Randy Shoup discusses the architecture of eBay. Topics discussed include eBay's architectural principles, horizontal and vertical partitioning, ACID vs. BASE, handling data inconsistency, distributed caching, updating eBay on the fly, architectural and coding standards, eBay's search infrastructure, grid computing, and SOA.
At RailsConf on Friday, Avi Bryant and Bob Walker of GemStone revealed plans for the MagLev project. MagLev will run Ruby on Rails within GemStone's distributed object technology. The MagLev VM, although only partially implemented, so far outperforms MRI 1.8.
Erlang has recently generated a lot of interest as a language that can deal both efficiently and elegantly with concurrency. In particular, there is no shared memory between "process" instances which only communicate via asynchronous messages. Nevertheless, Shared Memory Concurrency remains an intense research subject especially for multicore applications.
In a recent discussion Mark Little and Greg Pavlik discuss whether transaction coordinators and transaction protocols are necessary in the context of widely distributed units of work. Isn't the knowledge of state alignment patterns enough?
Sun's latest Project Tango release includes WS-AtomicTransaction and WS-Coordination support. They also have demonstrated interoperability .NET 3.0 clients.
The OASIS WS-TX technical committee held a face-to-face meeting last week at IBM Hursely. This is likely the last such meeting prior to final standardisation of WS-Coordination, WS-AtomicTransaction and WS-BusinessActivity.
ACID transactions don't work for long-lived use cases. This article documents historic approaches taken in the CORBA and J2EE communities toward extended transactions, how SOA is a more natural fit, and why WS-TX & WS-CAF may finally hold the answer.
