      • scanConsistency

        public QueryOptions scanConsistency​(QueryScanConsistency scanConsistency)
        Scan consistency for the query
        Parameters:
        scanConsistency - the index scan consistency to be used
        Returns:
        QueryOptions for further chaining

      • profile

        public QueryOptions profile​(QueryProfile profile)
        Set the profiling information level for query execution
        Parameters:
        profile - the query profile level to be used
        Returns:
        QueryOptions for further chaining

      • clientContextId

        public QueryOptions clientContextId​(String clientContextId)
        Adds a client context ID to the request, that will be sent back in the response, allowing clients to meaningfully trace requests/responses when many are exchanged.
        Parameters:
        clientContextId - the client context ID (null to send none)
        Returns:
        this QueryOptions for chaining.

      • metrics

        public QueryOptions metrics​(boolean metrics)
        If set to true (false being the default), the metrics object will be returned from N1QL and as a result provide insight into timings.
        Parameters:
        metrics - true if enabled, false otherwise (true = default).
        Returns:
        this QueryOptions for chaining.

      • scanWait

        public QueryOptions scanWait​(Duration wait)
        If the scan consistency has been chosen, does nothing. Otherwise, sets the maximum time the client is willing to wait for an index to catch up to the vector timestamp in the request.
        Parameters:
        wait - the duration.
        Returns:
        this QueryOptions for chaining.

      • maxParallelism

        public QueryOptions maxParallelism​(int maxParallelism)
        Allows to override the default maximum parallelism for the query execution on the server side.
        Parameters:
        maxParallelism - the maximum parallelism for this query, 0 or negative values disable it.
        Returns:
        this QueryOptions for chaining.

      • readonly

        public QueryOptions readonly​(boolean readonly)
        If set to true, it will signal the query engine on the server that only non-data modifying requests are allowed. Note that this rule is enforced on the server and not the SDK side. Controls whether a query can change a resulting record set. If readonly is true, then the following statements are not allowed: - CREATE INDEX - DROP INDEX - INSERT - MERGE - UPDATE - UPSERT - DELETE
        Parameters:
        readonly - true if readonly should be forced, false is the default and will use the server side default.
        Returns:
        this QueryOptions for chaining.

      • scanCap

        public QueryOptions scanCap​(int scanCap)
        Advanced: Maximum buffered channel size between the indexer client and the query service for index scans. This parameter controls when to use scan backfill. Use 0 or a negative number to disable.
        Parameters:
        scanCap - the scan_cap param, use 0 or negative number to disable.
        Returns:
        this QueryOptions for chaining.

      • pipelineBatch

        public QueryOptions pipelineBatch​(int pipelineBatch)
        Advanced: Controls the number of items execution operators can batch for Fetch from the KV.
        Parameters:
        pipelineBatch - the pipeline_batch param.
        Returns:
        this QueryOptions for chaining.

      • pipelineCap

        public QueryOptions pipelineCap​(int pipelineCap)
        Advanced: Maximum number of items each execution operator can buffer between various operators.
        Parameters:
