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.

Yesterday, the team at FoundationDB announced that they are open sourcing the FoundationDB Document Layer, a document-oriented database. The FoundationDB Document Layer is a stateless microserver which is backed by the scalable and transactional features of FoundationDB.

All data is stored as an ordered key-value data structure and can be remapped to custom data models or indexes by using user-written layer module API. Full-text indexes are designed to allow users to search within text strings. The FoundationDB SQL layer integrates with the Lucene full-text engine for full-text processing, index maintenance, and querying. Full-text indexes are currently disabled. Analytic frameworks (eg MapReduce) are outside the scope of the FoundationDB core. Install FoundationDB.

The FoundationDB API comes with a set of functions for discovering the storage locations of keys within your cluster. M mapIterable(AsyncIterable, Function) - Static method in class com.apple.foundationdb.async. Storing two access paths for each item is an example of an inverse index (see the pattern for Simple Indexes). You set both parts of the index in a single transactional function, as follows: @fdb .

2 BACKGROUND ON FOUNDATIONDB FoundationDB is a distributed, ordered key-value store that runs on clusters of commodity servers and provides ACID transactions over arbitrary sets of keys using optimistic con-currency control. Its architecture draws from the virtual synchrony paradigm [23, 26] whereby FoundationDB is com- 2019-01-14 · We have a variety of advanced index types, including aggregate indexes such as grouped counts, full text indexes, ordinal rank indexes, and extensible functional indexes. Where possible, our implementations leverage advanced FoundationDB features, such as atomic mutations. Install FoundationDB here. Once it is installed you should verify that you can run FDB and connect to it using fdbcli : $ fdbcli Using cluster file ` /usr/local/etc/foundationdb/fdb.cluster '.

FoundationDB - the open source, distributed, transactional key-value store - apple/foundationdb FoundationDB is multi-model, meaning you can store many types of data in a single database. All data is safely stored, distributed, and replicated in the Key-Value Store component. It is easy to install, grow, and manage, with a distributed architecture that gracefully scales out, and handles faults while acting like a single ACID database. Apple recently open-sourced FoundationDB, two years after acquiring the company and depriving the world of some promising technology.FoundationDB is a distributed key-value store featuring ACID transactions, painless scaling and easy fault tolerance, all tested with ridiculous thoroughness. FoundationDB is multimodel database, meaning you can store many types of data all in a single database, according to FoundationDB.
