Interface FeedClient

All Superinterfaces:

AutoCloseable, Closeable

public interface FeedClient
extends Closeable

Asynchronous feed client accepting document operations as JSON. The payload should be the same as the HTTP payload required by the /document/v1 HTTP API, i.e.,

     {
         "fields": {
             ...
         }
     }

Nested Classes

Modifier and Type	Interface	Description
static interface	FeedClient.CircuitBreaker	Allows slowing down or halting completely operations against the configured endpoint on high failure rates.
static enum	FeedClient.OperationType
static interface	FeedClient.RetryStrategy	Controls what to retry, and how many times.

Method Summary

Modifier and Type	Method	Description
static List<Result>	await(CompletableFuture<Result>... promises)	Same as await(List) except promises parameter is a vararg
static List<Result>	await(List<CompletableFuture<Result>> promises)	Waits for all feed operations to complete, either successfully or with exception.
FeedClient.CircuitBreaker.State	circuitBreakerState()	Current state of the circuit breaker.
default void	close()	Initiates graceful shutdown.
void	close(boolean graceful)	Shut down, and reject new operations.
CompletableFuture<Result>	put(DocumentId documentId, String documentJson, OperationParameters params)	Send a document put with the given parameters, returning a future with the result of the operation.
CompletableFuture<Result>	remove(DocumentId documentId, OperationParameters params)	Send a document remove with the given parameters, returning a future with the result of the operation.
OperationStats	stats()	Returns a snapshot of the stats for this feed client, such as requests made, and responses by status.
CompletableFuture<Result>	update(DocumentId documentId, String updateJson, OperationParameters params)	Send a document update with the given parameters, returning a future with the result of the operation.

Method Details

put

CompletableFuture<Result> put(DocumentId documentId,
 String documentJson,
 OperationParameters params)

Send a document put with the given parameters, returning a future with the result of the operation. Exceptional completion will use be an instance of FeedException or one of its sub-classes.

update

CompletableFuture<Result> update(DocumentId documentId,
 String updateJson,
 OperationParameters params)

Send a document update with the given parameters, returning a future with the result of the operation. Exceptional completion will use be an instance of FeedException or one of its sub-classes.

remove

CompletableFuture<Result> remove(DocumentId documentId,
 OperationParameters params)

Send a document remove with the given parameters, returning a future with the result of the operation. Exceptional completion will use be an instance of FeedException or one of its sub-classes.

await

static List<Result> await(List<CompletableFuture<Result>> promises)
                   throws MultiFeedException

Waits for all feed operations to complete, either successfully or with exception.

Returns:

list of results with the same ordering as the promises parameter

Throws:

MultiFeedException - if any operation fails

await

@SafeVarargs
static List<Result> await(CompletableFuture<Result>... promises)
                   throws MultiFeedException

Same as await(List) except promises parameter is a vararg

Throws:

MultiFeedException

• await(List)

stats

OperationStats stats()

Returns a snapshot of the stats for this feed client, such as requests made, and responses by status.

circuitBreakerState

FeedClient.CircuitBreaker.State circuitBreakerState()

Current state of the circuit breaker.

close

void close(boolean graceful)

Shut down, and reject new operations. Operations in flight are allowed to complete normally if graceful.

close

default void close()

Initiates graceful shutdown. See close(boolean).
