public interface AsyncBucket
Defines operations that can be executed asynchronously against a Couchbase Server bucket.
Note that only a subset of the provided operations are available for “memcached” type buckets. Also, some other operations are only available against specific versions of Couchbase Server.
Always apply a Observable.timeout(long, TimeUnit) of some form to add a boundary between the SDK as an integration point and the application. Networks are unreliable, servers can fail and the SDK contains bugs. With applying a timeout and reacting to them accordingly, application level code is less likely to fail.

CouchbaseEnvironment environment()
The CouchbaseEnvironment used.
Observable<com.couchbase.client.core.ClusterFacade> core()
Returns the underlying “core-io” library through its ClusterFacade.
Handle with care, with great power comes great responsibility. All additional checks which are normally performed by this library are skipped.
ClusterFacade from the “core-io” package.Observable<JsonDocument> get(String id)
Retrieves a JsonDocument by its unique ID.
If the document is found, a JsonDocument is returned. If the document is not found, the Observable completes without an item emitted.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - the unique ID of the document.Observable eventually containing the found JsonDocument.<D extends Document<?>> Observable<D> get(D document)
Retrieves any type of Document by its unique ID.
The document ID is taken out of the Document provided, as well as the target type to return. Note that not the same document is returned, but rather a new one of the same type with the freshly loaded properties.
If the document is found, a Document is returned. If the document is not found, the Observable completes without an item emitted.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.document - the source document from which the ID is taken and the type is inferred.Observable eventually containing the found Document.<D extends Document<?>> Observable<D> get(String id, Class<D> target)
Retrieves any type of Document by its unique ID.
This method differs from get(String) in that if a specific Document type is passed in, the appropriate Transcoder will be selected (and not JSON conversion).
If the document is found, a Document is returned. If the document is not found, the Observable completes without an item emitted.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - the unique ID of the document.target - the target document type to use.Observable eventually containing the found Document.Observable<Boolean> exists(String id)
Check whether a document with the given ID does exist in the bucket.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - the id of the document.<D extends Document<?>> Observable<Boolean> exists(D document)
Check whether a document with the given ID does exist in the bucket.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.document - the document where the ID is extracted from.Observable<JsonDocument> getFromReplica(String id, ReplicaMode type)
Retrieves one or more, possibly stale, representations of a JsonDocument by its unique ID.
Depending on the ReplicaMode selected, there can be none to four JsonDocument be returned from the Observable. If ReplicaMode.FIRST, ReplicaMode.SECOND or ReplicaMode.THIRD are selected zero or one documents are returned, if ReplicaMode.ALL is used, all configured replicas plus the master node may return a document.
If the document has not been replicated yet or if the replica or master are not available (because a node has been failed over), no response is expected from these nodes.
Since data is replicated asynchronously, all data returned from this method must be considered stale. If the appropriate ReplicateTo constraints are set on write and the operation returns successfully, then the data can be considered as non-stale.
Note that the returning JsonDocument responses can come in any order.
Because this method is considered to be a “last resort” call against the database if a regular get didn’t succeed, all errors are swallowed (but logged) and the Observable will return all successful responses.
id - id the unique ID of the document.type - the ReplicaMode to select.Observable eventually containing zero to N JsonDocuments.<D extends Document<?>> Observable<D> getFromReplica(D document, ReplicaMode type)

This method differs from getFromReplica(String, ReplicaMode) in that if a specific Document type is passed in, the appropriate Transcoder will be selected (and not JSON conversion).

id - id the unique ID of the document.type - the ReplicaMode to select.target - the target document type to use.Observable eventually containing zero to N Documents.Observable<JsonDocument> getAndLock(String id, int lockTime)
Retrieve and lock a JsonDocument by its unique ID.
If the document is found, a JsonDocument is returned. If the document is not found, the Observable completes without an item emitted.
This method works similar to get(String), but in addition it (write) locks the document for the given lock time interval. Note that this lock time is hard capped to 30 seconds, even if provided with a higher value and is not configurable. The document will unlock afterwards automatically.
Detecting an already locked document is done by checking for TemporaryLockFailureException. Note that this exception can also be raised in other conditions, always when the error is transient and retrying may help.
The returned Observable can error under the following conditions:
TemporaryLockFailureExceptionBackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - id the unique ID of the document.lockTime - the time to write lock the document (max. 30 seconds).Observable eventually containing the found JsonDocument.<D extends Document<?>> Observable<D> getAndLock(D document, int lockTime)
Retrieve and lock a Document by its unique ID.

Retrieve and lock a Document by its unique ID.
This method differs from getAndLock(String, int) in that if a specific Document type is passed in, the appropriate Transcoder will be selected (and not JSON conversion).

Detecting an already locked document is done by checking for TemporaryLockFailureException. Note that this exception can also be raised in other conditions, always when the error is transient and retrying may help.
The returned Observable can error under the following conditions: - In case of transient error, most probably because key is already locked: TemporaryLockFailureException - The producer outpaces the SDK: BackpressureException - The operation had to be cancelled while on the wire or the retry strategy cancelled it instead of retrying: RequestCancelledException - The server is currently not able to process the request, retrying may help: TemporaryFailureException - The server is out of memory: CouchbaseOutOfMemoryException - Unexpected errors are caught and contained in a generic CouchbaseException.
id - id the unique ID of the document.lockTime - the time to write lock the document (max. 30 seconds).target - the target document type to use.Observable eventually containing the found Document.Observable<JsonDocument> getAndTouch(String id, int expiry)
Retrieve and touch a JsonDocument by its unique ID.
If the document is found, a JsonDocument is returned. If the document is not found, the Observable completes without an item emitted.
This method works similar to get(String), but in addition it touches the document, which will reset its configured expiration time to the value provided.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - id the unique ID of the document.expiry - the new expiration time for the document.Observable eventually containing the found JsonDocument.<D extends Document<?>> Observable<D> getAndTouch(D document)
Retrieve and touch a Document by its unique ID.
If the document is found, a Document is returned. If the document is not found, the Observable completes without an item emitted.
This method works similar to get(Document), but in addition it touches the document, which will reset its configured expiration time set on the given document itself.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.document - the source document from which the ID and expiry is taken and the type is inferred.Observable eventually containing the found Document.<D extends Document<?>> Observable<D> getAndTouch(String id, int expiry, Class<D> target)
Retrieve and touch a Document by its unique ID.
This method differs from getAndTouch(String, int) in that if a specific Document type is passed in, the appropriate Transcoder will be selected (and not JSON conversion).
If the document is found, a JsonDocument is returned. If the document is not found, the Observable completes without an item emitted.
This method works similar to get(String, Class), but in addition it touches the document, which will reset its configured expiration time to the value provided.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.id - id the unique ID of the document.expiry - the new expiration time for the document.target - the target document type to use.Observable eventually containing the found Document.<D extends Document<?>> Observable<D> insert(D document)
Insert a Document if it does not exist already.
If the given Document (identified by its unique ID) already exists, the observable errors with a DocumentAlreadyExistsException. If the operation should also override the existing Document, upsert(Document) should be used instead. It will always either return a document or fail with an error.
The returned Document contains original properties, but has the refreshed CAS value set.
This operation will return successfully if the Document has been acknowledged in the managed cache layer on the master server node. If increased data durability is a concern, insert(Document, PersistTo, ReplicateTo) should be used instead.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionDocumentAlreadyExistsExceptionRequestTooBigExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.document - the Document to insert.Observable eventually containing a new Document.<D extends Document<?>> Observable<D> insert(D document, PersistTo persistTo, ReplicateTo replicateTo)
Insert a Document if it does not exist already and watch for durability constraints.
This method works exactly like insert(Document), but afterwards watches the server states if the given durability constraints are met. If this is the case, a new document is returned which contains the original properties, but has the refreshed CAS value set.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionDocumentAlreadyExistsExceptionRequestTooBigExceptionDurabilityException.TemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.A DurabilityException typically happens if the given amount of replicas needed to fulfill the durability constraint cannot be met because either the bucket does not have enough replicas configured or they are not available in a failover event. As an example, if one replica is configured and ReplicateTo.TWO is used, the observable is errored with a DurabilityException. The same can happen if one replica is configured, but one node has been failed over and not yet rebalanced (hence, on a subset of the partitions there is no replica available). It is important to understand that the original insert has already happened, so the actual insert and the watching for durability constraints are two separate tasks internally.
document - the Document to insert.persistTo - the persistence constraint to watch.replicateTo - the replication constraint to watch.Observable eventually containing a new Document.<D extends Document<?>> Observable<D> insert(D document, PersistTo persistTo)

document - the Document to insert.replicateTo - the replication constraint to watch.Observable eventually containing a new Document.<D extends Document<?>> Observable<D> upsert(D document)
Insert or overwrite a Document.
If the given Document (identified by its unique ID) already exists, it will be overridden by the current one. The returned Document contains original properties, but has the refreshed CAS value set.
Please note that this method will not use the Document.cas() for optimistic concurrency checks. If this behavior is needed, the replace(Document) method needs to be used.
This operation will return successfully if the Document has been acknowledged in the managed cache layer on the master server node. If increased data durability is a concern, upsert(Document, PersistTo, ReplicateTo) should be used instead.
The returned Observable can error under the following conditions:

Insert or overwrite a Document and watch for durability constraints.
This method works exactly like upsert(Document), but afterwards watches the server states if the given durability constraints are met. If this is the case, a new document is returned which contains the original properties, but has the refreshed CAS value set.

Please note that this method will not use the Document.cas() for optimistic concurrency checks. If this behavior is needed, the replace(Document, ReplicateTo) method needs to be used.
The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionRequestTooBigExceptionDurabilityException.TemporaryFailureExceptionCouchbaseOutOfMemoryExceptionCouchbaseException.A DurabilityException typically happens if the given amount of replicas needed to fulfill the durability constraint cannot be met because either the bucket does not have enough replicas configured or they are not available in a failover event. As an example, if one replica is configured and ReplicateTo.TWO is used, the observable is errored with a DurabilityException. The same can happen if one replica is configured, but one node has been failed over and not yet rebalanced (hence, on a subset of the partitions there is no replica available). It is important to understand that the original upsert has already happened, so the actual upsert and the watching for durability constraints are two separate tasks internally.
document - the Document to upsert.replicateTo - the replication constraint to watch.Observable eventually containing a new Document.<D extends Document<?>> Observable<D> replace(D document)
Replace a Document if it does already exist.
If the given Document (identified by its unique ID) does not exist already, the method errors with a DocumentDoesNotExistException. If the operation should also insert the Document, upsert(Document) should be used instead. It will always either return a document or fail with an error.
The returned Document contains original properties, but has the refreshed CAS value set.
This operation will return successfully if the Document has been acknowledged in the managed cache layer on the master server node. If increased data durability is a concern, replace(Document, PersistTo, ReplicateTo) should be used instead.

Prepend a Documents content to an existing one.
The Document returned explicitly has the Document.content() set to null, because the server does not return the prepended result, so at this point the client does not know how the Document now looks like. A separate get(Document) call needs to be issued in order to get the full current content.
If the Document does not exist, it needs to be created upfront. Note that JsonDocuments in all forms are not supported, it is advised that the following ones are used:

The returned Observable can error under the following conditions:
BackpressureExceptionRequestCancelledExceptionRequestTooBigExceptionDocumentDoesNotExistExceptionTemporaryFailureExceptionCouchbaseOutOfMemoryExceptionDurabilityException.CouchbaseException.A DurabilityException typically happens if the given amount of replicas needed to fulfill the durability constraint cannot be met because either the bucket does not have enough replicas configured or they are not available in a failover event. As an example, if one replica is configured and ReplicateTo.TWO is used, the observable is errored with a DurabilityException. The same can happen if one replica is configured, but one node has been failed over and not yet rebalanced (hence, on a subset of the partitions there is no replica available). It is important to understand that the original prepend has already happened, so the actual prepend and the watching for durability constraints are two separate tasks internally.

Invalidates and clears the internal query cache.
This method can be used to explicitly clear the internal N1QL query cache. This cache will be filled with non-adhoc query statements (query plans) to speed up those subsequent executions.
Triggering this method will wipe out the complete cache, which will not cause an interruption but rather all queries need to be re-prepared internally. This method is likely to be deprecated in the future once the server side query engine distributes its state throughout the cluster.
The returned Observable will not error out under any conditions.
Observable<AsyncBucketManager> bucketManager()
Provides access to the AsyncBucketManager for administrative access.
The manager lets you perform operations such as flushing a bucket or creating and managing design documents.
@InterfaceAudience.Public @InterfaceStability.Experimental Observable<AsyncRepository> repository()
The Repository provides access to full object document mapping (ODM) capabilities.
It allows you to work with POJO entities only and use annotations to customize the behaviour and mapping characteristics.
Observable<Boolean> close()
Closes the AsyncBucket.
Observable eventually containing a new Boolean after close.boolean isClosed()
Returns true if this bucket is already closed, false if it is still open.
