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. Generally the foundationdb::init function will be enough to

All data is safely stored, distributed, and replicated in the Key … Because FoundationDB supports global indexing and ACID transactions, the database itself will handle updates to the relevant data without intervention or management by the application. (And because an index is just like regular data, it has the same properties, like ordering, for efficient access.) Defining indexes; Performing record CRUD; Querying records; To keep the guide simple, we will not cover: Modifying a schema; Using advanced index and query functionality; Setup.

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. Later, you can 2021-04-09 · Transaction is a handle to a FoundationDB transaction. Transaction is a lightweight object that may be efficiently copied, and is safe for concurrent use by multiple goroutines. In FoundationDB, a transaction is a mutable snapshot of a database. 2015-02-09 · In FoundationDB, the following features are available: default roles, custom roles.

It supports simple predicate queries that use those indexes. Each record store is an extent of records described by meta-data.

FDB does not automatically index your data, but you can write a layer (like this one) to index your data. In a transaction, you write a key like “users/1” with a value of “bob” and then write another key like “users/bob/1” with no value.

Secondary Indexes: Secondary indexes enable flexible and efficient searches using non-primary key attributes. In distributed databases, secondary indexes are typically partitioned across each node that hold data objects, and hence secondary index queries can suffer from performance limits. In FoundationDB, secondary indexes are supported.

FoundationDB is a scalable and fault tolerant database that supports multiple data models using high performance multi-key ACID transactions.

The product was designed around a "core" database, with additional features supplied in "layers." The core database exposes an ordered key-value store with transactions. 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. 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.
