Exemplos e Demos



Conecanto ao Oracle NoSQL

String storeName = "kvstore";

String hostName = "localhost:5000";

KVStoreConfig kvConfig = new KVStoreConfig(storeName, hostName);

try (KVStore store = KVStoreFactory.getStore(kvConfig)) {

// ... Manipula a store

}



Exemplo de CRUD

// Coloca nova chave/valor se ainda não existe

Key key = Key.createKey("Katana");

String valString = "sword";

store.putIfAbsent(key, Value.createValue(valString.getBytes()));

// Deleta esta chave (e valor) do banco de dados

store.delete(key);



Exemplo de CRUD

// Leitura de dados do banco

ValueVersion retValue = store.get(key);

// Atualiza este item somente se a versão for a mesma que a lida

String newvalString = "Really nice sword";

Value newval = Value.createValue(newvalString.getBytes());

store.putIfVersion(key, newval, retValue.getVersion());



Apache Avron – Definição de Schemas

• Framework para serialização de dados

• Features

– Estruturas de dados ricas

– Compacta, rápida, formato de dados binário

– Container file para persistir dados

– Suporte a RPC

– Integrado ao Oracle NoSQL


JSON format


Schema Definition em JSON

{

"type": "record",

"namespace": "schema.namespace",

"name": "schema.name",

"fields": [

{ "name": "field1", "type": "string" },

{ "name": "field2", "type": "int" }

]

}


Com Apache Avron

$> java -jar lib/kvstore.jar runadmin -host localhost -port 5000 kv-> ddl add-schema -file sample-schema.avsc


Incluindo JSON dentro do Oracle NoSQL

ObjectNode name = JsonNodeFactory.instance.objectNode(); name.put("first", "Percival"); name.put("last", "Lowell"); JsonRecord record = new JsonRecord(member, memberInfoSchema); store.put(key, binding.toValue(record));



Bonus: Acesso via REST

• fka Oracle APEX Listener

• Futura versão 3.0 do Oracle REST Data Services – Roadmap

– Oracle NoSQL

– Oracle Database

– JSON format

– Automatic linkage master-detail

– PL/SQL API to generate REST services

– Test environment on Oracle SQL Developer
