+= Query
+:description: Configure Query Service settings to manage CURL() access, disk and memory quotas, logging, and optimizer settings.
+
+[abstract]
+{description}
+
+== Overview
+
+You can configure the Query Service for your cluster using the menu:Settings[] tab on the Couchbase Server Web Console.
+
+Use these settings to control CURL() endpoint access, set temporary disk usage limits, manage resources, and set query execution and logging parameters.
+
+To configure the Query Service settings:
+
+. In the Couchbase Server Web Console, click menu:Settings[].
+. Select the *Query* tab.
+. Update the required settings and click btn:[Save].
+
+== CURL Function Access
+
+The `CURL()` function allows {sqlpp} queries to send HTTP requests to external endpoints. 
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *CURL() Function Access*
+a| Controls whether `CURL()` can access any external URL or only specified URLs.
+
+Select 1 of the following options: 
+
+* *Restricted*: Limits access to only the URLs listed in *Allowed CURL URLs*. 
+* *Unrestricted*: Allows access to any URL. 
+| Unrestricted 
+
+| *Allowed CURL URLs*
+a| The URLs `CURL()` can access when *CURL() Function Access* is set to *Restricted*. 
+
+* To add a URL, click btn:[+].
+You can add multiple URLs.
+* To remove a URL, click btn:[-] next to it.
+| None
+
+| *Disallowed CURL URLs*
+a| The URLs `CURL()` can never access, regardless of the *CURL() Function Access* setting.
+
+* To add a URL, click btn:[+].
+You can add multiple URLs.
+* To remove a URL, click btn:[-] next to it.
+| None
+|===
+
+== Temporary Disk Usage
+
+When an index scan returns more data than fits in memory, the indexer writes the remaining data to temporary backfill files on disk. 
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *Query Temp Disk Path*
+| The absolute path where the indexer writes temporary backfill files. 
+The path must already exist on the target node.
+|`/opt/couchbase/var/lib/couchbase/tmp`
+
+| *Quota*
+a| The maximum size, in mebibytes (MiB), allowed for temporary backfill files.
+
+* To turn off backfill, set the value to `0`.
+* To allow unlimited backfill, up to the maximum available disk space, set the value to `-1`.
+|`5120`
+
+|===
+
+NOTE: Global Secondary Indexes (GSIs) do not perform backfill operations if *Quota* is set to `0` or lower. 
+To enable backfill for GSIs, set *Quota* to a large positive value (such as `102400`).
+
+== Resource Limits
+
+Configure parameters to manage memory, execution limits, and query timeouts.
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *Pipeline Batch*
+| Number of items the Query Service batches together when fetching data from the Data Service.
+| `16`
+
+| *Pipeline Cap*
+| Maximum number of items the Query Service buffers during a single fetch.
+| `512`
+
+| *Scan Cap*
+| Maximum size, in items, of the buffered channel between the indexer client and the Query Service during an index scan.
+| `512`
+
+| *Timeout (ns)*
+| Maximum request execution time in nanoseconds before timing out. 
+
+To turn off timeouts, set the value to `0`.
+| `0`
+
+| *Prepared Limit*
+| Maximum number of prepared statements retained in the Query Service cache.
+| `16384`
+
+| *Max Parallelism*
+| Maximum number of index partitions the Query Service uses for parallel aggregation.
+| `1`
+
+| *N1QL Feature Controller*
+| Bitmask value used to enable or disable specific query engine features and controls. 
+
+WARNING: Do not change *N1QL Feature Controller* without guidance from Couchbase technical support.
+| `76`
+
+| *Transaction Timeout (duration)*::
+| Maximum duration (in milliseconds) allowed for a transaction before timing out.
+| `0ms`
+
+| *Memory Quota (MB)*
+| Maximum amount of memory (in megabytes) allocated to processing a query.
+| `0`
+|===
+
+== Logging and Completed Requests
+
+The Query Service maintains a log of completed requests.
+Use the following options to control query logging. 
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *Completed Limit*
+| Maximum number of requests retained in the completed requests catalog.
+| `4000`
+
+| *Completed Threshold*
+| Minimum query duration (in milliseconds) required for a completed request to be logged. 
+The Query Service omits queries that finish faster than this threshold.
+| `1000`
+
+| *Log Level*
+| The logging level for the Query Service logger.
+| `Info`
+|===
+
+== Replica Usage
+
+Configure read options for high availability and failover scenarios. 
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *Use Replica*
+a| Controls whether queries can fall back to reading data from replica buckets when the active bucket is unavailable. 
+
+* *Unset*: Read from replica is controlled at the request level.
+* *On*: Read from replica is enabled for all queries, but a request can still turn it off.
+* *Off*: Read from replica is turned off for all queries and cannot be overridden at the request level.
+|`Unset`
+|===
+
+NOTE: Do not enable *Use Replica* if your workload requires consistent results. 
+Only `SELECT` outside of a transaction can read from a replica. 
+In addition, KV range scans cannot start on a replica vBucket.
+If a query uses a sequential scan and a data node becomes unavailable, the query might return an error even when read from replica is enabled.
+
+== Query Optimization
+
+Configure rules for cost optimizer behavior and replica usage. 
+
+[cols="1,2,1",options="header"]
+|===
+| Setting | Description | Default Value
+
+| *Use Cost-Based Optimizer*
+a| Determines whether to use the xref:n1ql:n1ql-language-reference/cost-based-optimizer.adoc[cost-based optimizer] for execution planning.
+
+* To enable the optimizer, select *Use Cost-Based Optimizer*. 
+* To disable the optimizer, clear *Use Cost-Based Optimizer*.
+
+| Selected (Enabled)
+|===
