Retries, LB, Failover and support of GraphQL

Configuration changes

Astra allows now multiple regions. the configuration evolved to be able to cope with them. The secureConnectBundle will now be a folder, the others regions will be retrieved dynamically.

AstraClient client = AstraClient.builder()
   .withDatabaseId("ABC")         // Unique identifier for your instance
   .withDatabaseRegion("DEF")  // Cloud Provider region picked for you instance
   .withKeyspace("KS")             // (optional) Set your keyspace
   .withToken("token")
   .withClientId("clientId")         // Will be used as your username
   .withClientSecret("clientSecret")     // Will be used as your password
   .build();

Retries and request Configuration

At Stargate level, you can now specified a fined-grained configuration for the HTTP Client.

StargateClient.builder()
 //...
   .withHttpRetryConfig(new RetryConfigBuilder()
      .retryOnAnyException()
      .withDelayBetweenTries(Duration.ofMillis(100))
      .withExponentialBackoff()
      withMaxNumberOfTries(3)
      .build())
   .withHttpRequestConfig(RequestConfig.custom()
      .setCookieSpec(StandardCookieSpec.STRICT)
      .setExpectContinueEnabled(true)
      .setConnectionRequestTimeout(Timeout.ofSeconds(2))
      .setConnectTimeout(Timeout.ofSeconds(2))
      .setTargetPreferredAuthSchemes(Arrays.asList(StandardAuthScheme.NTLM, StandardAuthScheme.DIGEST))
      .build()
);

GraphQL Support

You can now query dynamically the GraphQL endpoints.

// Given a stargateClient
CqlSchemaClient cqlSchemaClient = stargateClient.apiGraphQL().cqlSchema();
cqlSchemaClient.queryListKeyspaces());

Spring Data-Ish Repositories with Document API

// Random bean
Person johnConnor = new Person("John", "Connor", 20, new Address("Syberdyn", 75000));

// Create the repository providing `namespace` name and `collection` name
StargateDocumentRepository<Person> personRepo = new StargateDocumentRepository<Person>( 
  stargateClient.apiDocument().namespace("namespaceA").collection("collectionB"), 
  Person.class);

// insert
String docId = personRepo.insert(johnConnor);

// Let's the magic happens
Stream<Document<Person>> records = personRepository.findAll();
