∙ 0 ∙ share . The FoundationDB Record Layer is an open sourceopen source FoundationDB, set-up by Nick Lavezzo, Dave Rosenthal and Dave Schrerer in 2009, say that they are squaring the circle. Their new NoSQL platform, Key Value Store, released late last December, was launched into a frenzied market with a ferocious appetite for super-scalable db engines that can support ultra-heavy workloads but also demands consistency and reliability. Installation instructions for the segment/foundationdb package repository. FoundationDB is a NoSQL database with a shared nothing architecture. Designed around a "core" ordered key-value database, additional features and data models are supplied in layers. The key-value database, as well as all layers, supports full, cross-key and cross-server ACID transactions.

Index builds The Document Layer can perform index builds in either the background or the foreground. Unlike in MongoDB®, there is no downside to either of these options – backgrounded builds are no less space efficient than Online index builds in the Document Layer perform the exact same operations whether backgrounded or not – the only difference made by the backgroundparameter in an createIndexoperation is whether the command returns to the client This is a wrapper library around the FoundationDB (Fdb) C API. It implements futures based interfaces over the Fdb future C implementations. FoundationDB tries to balance latency and bandwidth by requesting data for iteration in batches. The Mode field of the RangeOptions struct allows a client to customize this performance tradeoff by providing extra information about how the iterator will be used.

Due to limitations in the C API, the Client and it's associated Network can only be initialized and run once per the life of a process.

By using the key ordering of FoundationDB, we can store indexes so that an index query can return multiple matches using a single efficient range read operation. By updating the data element and all of its associated indexes together within a single ACID transaction we can guarantee that the data and indexes stay in sync. FoundationDB is a scalable and fault tolerant database that supports multiple data models using high performance multi-key ACID transactions. The FoundationDB API comes with a set of functions for discovering the storage locations of keys within your cluster.

supported by FoundationDB. Tuples FoundationDB’s keys are ordered, making tuples a particulary useful tool for data modeling. FoundationDB supports tuples by providing a built-in layer (available in each language binding) to encode tuples into keys. This layer lets you store data using a tuple like (state, county) as a key.
