Method Details
-
rows
rx.Observable<AsyncN1qlQueryRow> rows()- Returns:
- an async stream of each row resulting from the query (empty if fatal errors occurred).
-
signature
rx.Observable<Object> signature()- Returns:
- an async single-item representing the signature of the results, that can be used to
learn about the common structure of each
row
. This signature is usually aJsonObject
, but could also be any JSON-valid type like a boolean scalar,JsonArray
...
-
info
rx.Observable<N1qlMetrics> info()- Returns:
- an async single item describing some metrics/info about the execution of the query.
-
profileInfo
rx.Observable<JsonObject> profileInfo()- Returns:
- an async single item describing some profiling info about the execution of the query.
-
parseSuccess
boolean parseSuccess()Immediately denotes initial parsing success of the query. As rows are processed, it could be that a late failure occurs. SeefinalSuccess()
for the end of processing status.- Returns:
- true if the query could be parsed, false if it short-circuited due to syntax/fatal error.
-
status
rx.Observable<String> status()Asynchronously returns the final status of the query. For example, a successful query will return "success
" (which is equivalent tofinalSuccess()
returning true). Other statuses include (but are not limited to) "fatal
" when fatal errors occurred and "timeout
" when the query timed out on the server side but not yet on the client side. Receiving a (single) value for status means the query is over. -
finalSuccess
rx.Observable<Boolean> finalSuccess()Asynchronously denotes the success or failure of the query. It could fail slower than withparseSuccess()
, for example if a fatal error comes up while streaming the results to the client. Receiving a (single) value for finalSuccess means the query is over. -
errors
rx.Observable<JsonObject> errors()- Returns:
- an async stream of errors or warnings encountered while executing the query.
-
requestId
String requestId()- Returns:
- the requestId generated by the server
-
clientContextId
String clientContextId()- Returns:
- the clientContextId that was set by the client (could be truncated to 64 bytes of UTF-8 chars)
-
