- All Implemented Interfaces:

,CouchbaseResponse
@Uncommitted @Public public class GenericAnalyticsResponse extends AbstractCouchbaseResponse
The base response for Analytics (SQL++) requests. Response is divided into sub-sections, each of which
can be asynchronously fed. They are represented as
Observable
, most of them of
ByteBuf
. Note that it is important that these streams are consumed and their ByteBuf released.
In order to reuse the values of a section but still correctly release the ByteBuf, the best is to
convert them into an appropriate gc-able value, release the buffer and cache the resulting stream.
If one isn't interested in a particular sub-section, it should still be released by subscribing a
Buffers.BYTE_BUF_RELEASER
to its stream.-

Method Details
-
rows
Contains oneByteBuf
for each result item returned by the server. Each item is a JSON object. -
signature
Contains a singleByteBuf
representing the Analytics json signature of the results. May not appear at all if there are no results (in case of fatal errors for example). -
errors
If there were errors and/or warnings while executing the query, contains aByteBuf
for each error and each warning. These are JSON objects, that should at least contain a 'msg' and a 'code'. -
queryStatus
-
info
Contains a singleByteBuf
representing the JSON object of query execution metrics (or empty if metrics haven't been activated). -
requestId
- Returns:
- the UUID for this request, can be used on the server side for tracing.
-
clientRequestId
- Returns:
- the client-provided identifier if provided in the request, empty string otherwise.
-
handle
Contains the deferred handle url
