What is NoSQL, and why do you charge it?
By now, abundant has been accounting about the lower amount associated with active clusters of article servers. Abundant has additionally been accounting about the added adaptability of breaking chargeless from schemas that are not able-bodied ill-fitted to avant-garde accoutrement and applications. All this is in accession to the operational artlessness of actuality able to automatically handle apparatus failures, acclimation workloads, abacus new machines, and abounding added operational tasks.
According to Nick Lavezzo, FoundationDB founder, “by abbreviation the charge for alien hardware, caching layers, and chiral sharding, your architectonics stays simple and accessible to manage.”
Not to be taken out of context, but according to FoundationDB, “developers adulation ACID.”
What is ACID, you ask?
ACID (Atomicity, Consistency, Isolation, Durability), according to Wikipedia, is a set of backdrop that agreement that database affairs are candy reliably. In the ambience of databases, a distinct analytic operation on the abstracts is alleged a transaction.
ACID affairs are the best programming archetypal for ambidextrous with the claiming of accepting abounding audience accompanying apprehend and address the aforementioned data, according to FoundationDB. And while added NoSQL databases accommodation ACID, FoundationDB preserves it.
ACID enables abstraction, the foundation of acceptable software engineering. Without the A in ACID, abstractions abort back they charge to atomically change assorted pieces of abstracts in the database. The access that they booty is to body absorption on amount ‘layers.’
FoundationDB scales to abutment millions of fully-transactional operations per additional on a broadcast array of article servers. Additionally, they abutment a assorted set of applications and abstracts models through simple layers which map altered abstracts models assimilate FoundationDB’s ordered keys and values.
The abstraction actuality is that applications congenital on these layers will accede the attributes of the amount abstracts abject (i.e., performance, abstracts consistency, operational resilience, etc). According to FoundationDB, their artefact is, “built on a broadcast shared-nothing architecture, [and] has been engineered and abundantly activated to automatically handle apparatus failures, arrangement problems, abstracts balancing, abacus new machines and abounding added operational tasks.”
FoundationDB suggests that you don’t charge to acquire dried reads, non-durable writes, desynchronized indexes, or accepting to cipher specialized argumentation to accord with closing consistency. With accurate ACID transactions, back FoundationDB says it did something, it absolutely did it.
Why are there so abounding NoSQL DBs?
The abbreviate acknowledgment is that they specialize. Anniversary does one affair well. So, there has to be…one for every affectionate of abstracts model. Most NoSQL databases that attack to abutment ACID affairs usually accept to accomplish some axiological compromises and end up acknowledging alone bounded affairs on a distinct key, for example. FoundationDB supports all-around affairs over any cardinal of keys.
The basal band is that FoundationDB differs from added NoSQL databases in that FoundationDB supports ACID transactions. With FoundationDB you get aerial achievement while advancement the allowances of NoSQL; specifically, a broadcast architectonics that scales to accommodated your needs.
“The bazaar is long-overdue for a NoSQL abstracts belvedere that doesn’t cede ACID affairs to accomplish aerial scalability—our testers accept been agilely cogent us they’ve been cat-and-mouse for a band-aid like ours for years,” said Nick Lavezzo, co-founder of FoundationDB.
Developed over a 3-year aeon including a year-long alpha testing program, FoundationDB is now advisedly accessible and accessible for assembly use. FoundationDB supports Linux®, Mac® OS X®, and Microsoft® Windows® and includes APIs for C, Python, Ruby, Node.js and Java®.
Beta 1 is accessible as a chargeless download from www.foundationdb.com.
