FoundationDB delivers serializable isolation and external consistency for all transactions. Backgrounded index builds are supported as a compatibility option, and the current status of a backgrounded build can be determined by performing a read on the system.indexes virtual collection. The Document Layer has added several fields to the index metadata – including status (which should be one of building, ready, or error). 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.

FoundationDB is a free and open-source multi-model distributed NoSQL database developed by Apple Inc. with a shared-nothing architecture. 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.

Indexes and primary keys can be defined either via protobuf options or programmatically. 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. supported by FoundationDB. Tuples FoundationDB’s keys are ordered, making tuples a particulary useful tool for data modeling.

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.)

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 .

The FoundationDB Record Layer is an open source library that provides a record-oriented data store with semantics similar to a relational database implemented on top of FoundationDB, an ordered, transactional key-value store. The Record Layer provides a lightweight, highly extensible way to store structured data.

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. 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.
