NoSQL Database Abstraction

One interface for document databases and one for key/value stores, whatever the service behind them. The implementation supports:

• MongoDB (document-based)
• AWS DynamoDB (key/value)
• S3-Like Storage (key/value)
• Cloudflare KV (key/value)

Anydataset is an agnostic data source abstraction layer in PHP. See more about Anydataset here.

Why

MongoDB, DynamoDB, S3 and Cloudflare KV each come with their own SDK and their own way to read, write and list. Storing a file in S3 today and in Cloudflare KV tomorrow means rewriting every call.

Anydataset NoSQL defines two contracts, NoSqlInterface for documents and KeyValueInterface for key/value stores, and picks the service from the connection URI:

$store = Factory::getInstance('s3://key:secret@us-east-1/my-bucket');        // AWS S3
$store = Factory::getInstance('kv://user:token@account/namespace');          // Cloudflare KV
$store = Factory::getInstance('dynamodb://key:secret@host/table');           // DynamoDB

$store->put('invoice-42', $pdf);
$pdf = $store->get('invoice-42');

• Change the service with the URI, not the code that uses it.
• Same iterator as the rest of AnyDataset. getIterator() returns the same rows as a database or a file, and document queries use the same IteratorFilter.

Features

• Access both document-based and key/value repositories with consistent interfaces
• NoSQL document-based databases accessed through NoSqlInterface
• Key/Value stores accessed through KeyValueInterface
• Unified connection string format based on URIs
• Type-safe DynamoDB attribute definitions using enums

Connection Based on URI

The connection string for databases is based on URL.

See below the current implemented drivers:

Datasource	Connection String
MongoDB	mongodb://username:password@hostname:port/database
S3	s3://accesskey:secretkey@region/bucket?params
Cloudflare KV	kv://username:password@accountid/namespaceid
AWS DynamoDB	dynamodb://accesskey:secretkey@hostname/tablename?params
