-In 8.0, the top-level `body` parameter that was available on all API functions <<remove-body-key,was deprecated>>. In 9.0 this property is completely removed.

-===== Remove the default 30-second timeout on all requests sent to Elasticsearch
+==== Fixes
 
-Setting HTTP timeouts on Elasticsearch requests goes against Elastic's recommendations. See <<timeout-best-practices>> for more information.

+===== Improved Cloud ID parsing
+
+When using a Cloud ID as the `cloud` parameter to instantiate the client, that ID was assumed to be in the correct format. New assertions have been added to verify that format and throw a `ConfigurationError` if it is invalid. See https://github.com/elastic/elasticsearch-js/issues/2694[#2694].

 === Timeout best practices
 
-Starting in 9.0.0, this client is configured to not time out any HTTP request by default. {es} will always eventually respond to any request, even if it takes several minutes. Reissuing a request that it has not responded to yet can cause performance side effects. See the {ref}/modules-network.html#_http_client_configuration[official {es} recommendations for HTTP clients] for more information.
+This client is configured by default to operate like many HTTP client libraries do, by using a relatively short (30 second) timeout on all requests sent to {es}, raising a `TimeoutError` when that time period has elapsed without receiving a response. However, {es} will always eventually respond to any request, even if it takes several minutes. The {ref}/modules-network.html#_http_client_configuration[official {es} recommendation] is to disable response timeouts entirely by default.
 
-Prior to 9.0, this client was configured by default to operate like many HTTP client libraries do, by using a relatively short (30 second) timeout on all requests sent to {es}, raising a `TimeoutError` when that time period elapsed without receiving a response.
+Since changing this default would be a breaking change, we won't do that until the next major release. In the meantime, here is our recommendation for properly configuring your client:
 
-If your circumstances require you to set timeouts on Elasticsearch requests, setting the `requestTimeout` value to a millisecond value will cause this client to operate as it did prior to 9.0.
+* Ensure keep-alive is enabled; this is the default, so no settings need to be changed, unless you have set `agent` to `false` or provided an alternate `agent` that disables keep-alive
+* If using the default `UndiciConnection`, disable request timeouts by setting `timeout` to `0`
+* If using the legacy `HttpConnection`, set `timeout` to a very large number (e.g. `86400000`, or one day)

     * Forget a follower. Remove the cross-cluster replication follower retention leases from the leader. A following index takes out retention leases on its leader index. These leases are used to increase the likelihood that the shards of the leader index retain the history of operations that the shards of the following index need to run replication. When a follower index is converted to a regular index by the unfollow API (either by directly calling the API or by index lifecycle management tasks), these leases are removed. However, removal of the leases can fail, for example when the remote cluster containing the leader index is unavailable. While the leases will eventually expire on their own, their extended existence can cause the leader index to hold more history than necessary and prevent index lifecycle management from performing some operations on the leader index. This API exists to enable manually removing the leases when the unfollow API is unable to do so. NOTE: This API does not stop replication by a following index. If you use this API with a follower index that is still actively following, the following index will add back retention leases on the leader. The only purpose of this API is to handle the case of failure to remove the following retention leases after the unfollow API is invoked.

Once the excluded nodes have stopped, clear the voting configuration exclusions with `DELETE /_cluster/voting_config_exclusions`. This API waits for the nodes to be fully removed from the cluster before it returns. If your cluster has voting configuration exclusions for nodes that you no longer intend to remove, use `DELETE /_cluster/voting_config_exclusions?wait_for_removal=false` to clear the voting configuration exclusions without waiting for the nodes to leave the cluster. A response to `POST /_cluster/voting_config_exclusions` with an HTTP status code of 200 OK guarantees that the node has been removed from the voting configuration and will not be reinstated until the voting configuration exclusions are cleared by calling `DELETE /_cluster/voting_config_exclusions`. If the call to `POST /_cluster/voting_config_exclusions` fails or returns a response with an HTTP status code other than 200 OK then the node may not have been removed from the voting configuration. In that case, you may safely retry the call. NOTE: Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or when removing fewer than half of the master-eligible nodes.

You can also configure dynamic settings locally on an unstarted or shut down node in `elasticsearch.yml`. Updates made with this API can be persistent, which apply across cluster restarts, or transient, which reset after a cluster restart. You can also reset transient or persistent settings by assigning them a null value. If you configure the same setting using multiple methods, Elasticsearch applies the settings in following order of precedence: 1) Transient setting; 2) Persistent setting; 3) `elasticsearch.yml` setting; 4) Default setting value. For example, you can apply a transient setting to override a persistent setting or `elasticsearch.yml` setting. However, a change to an `elasticsearch.yml` setting will not override a defined transient or persistent setting. TIP: In Elastic Cloud, use the user settings feature to configure all cluster settings. This method automatically rejects unsafe settings that could break your cluster. If you run Elasticsearch on your own hardware, use this API to configure dynamic cluster settings. Only use `elasticsearch.yml` for static cluster settings and node settings. The API doesn’t require a restart and ensures a setting’s value is the same on all nodes. WARNING: Transient cluster settings are no longer recommended. Use persistent cluster settings instead. If a cluster becomes unstable, transient settings can clear unexpectedly, resulting in a potentially undesired cluster configuration.

For example, a shard can be moved from one node to another explicitly, an allocation can be canceled, and an unassigned shard can be explicitly allocated to a specific node. It is important to note that after processing any reroute commands Elasticsearch will perform rebalancing as normal (respecting the values of settings such as `cluster.routing.rebalance.enable`) in order to remain in a balanced state. For example, if the requested allocation includes moving a shard from node1 to node2 then this may cause a shard to be moved from node2 back to node1 to even things out. The cluster can be set to disable allocations using the `cluster.routing.allocation.enable` setting. If allocations are disabled then the only allocations that will be performed are explicit ones given using the reroute command, and consequent allocations due to rebalancing. The cluster will attempt to allocate a shard a maximum of `index.allocation.max_retries` times in a row (defaults to `5`), before giving up and leaving the shard unallocated. This scenario can be caused by structural problems such as having an analyzer which refers to a stopwords file which doesn’t exist on all nodes. Once the problem has been corrected, allocation can be manually retried by calling the reroute API with the `?retry_failed` URI query parameter, which will attempt a single retry round for these shards.

You can run a single count API search across multiple data streams and indices. The operation is broadcast across all shards. For each shard ID group, a replica is chosen and the search is run against it. This means that replicas increase the scalability of the count.

 /**
   * Delete a document. Remove a JSON document from the specified index. NOTE: You cannot send deletion requests directly to a data stream. To delete a document in a data stream, you must target the backing index containing the document. **Optimistic concurrency control** Delete operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the `if_seq_no` and `if_primary_term` parameters. If a mismatch is detected, the operation will result in a `VersionConflictException` and a status code of `409`. **Versioning** Each document indexed is versioned. When deleting a document, the version can be specified to make sure the relevant document you are trying to delete is actually being deleted and it has not changed in the meantime. Every write operation run on a document, deletes included, causes its version to be incremented. The version number of a deleted document remains available for a short time after deletion to allow for control of concurrent operations. The length of time for which a deleted document's version remains available is determined by the `index.gc_deletes` index setting. **Routing** If routing is used during indexing, the routing value also needs to be specified to delete a document. If the `_routing` mapping is set to `required` and no routing value is specified, the delete API throws a `RoutingMissingException` and rejects the request. For example: ``` DELETE /my-index-000001/_doc/1?routing=shard-1 ``` This request deletes the document with ID 1, but it is routed based on the user. The document is not deleted if the correct routing is not specified. **Distributed** The delete operation gets hashed into a specific shard ID. It then gets redirected into the primary shard within that ID group and replicated (if needed) to shard replicas within that ID group.

 /**
   * Get a document by its ID. Get a document and its source or stored fields from an index. By default, this API is realtime and is not affected by the refresh rate of the index (when data will become visible for search). In the case where stored fields are requested with the `stored_fields` parameter and the document has been updated but is not yet refreshed, the API will have to parse and analyze the source to extract the stored fields. To turn off realtime behavior, set the `realtime` parameter to false. **Source filtering** By default, the API returns the contents of the `_source` field unless you have used the `stored_fields` parameter or the `_source` field is turned off. You can turn off `_source` retrieval by using the `_source` parameter: ``` GET my-index-000001/_doc/0?_source=false ``` If you only need one or two fields from the `_source`, use the `_source_includes` or `_source_excludes` parameters to include or filter out particular fields. This can be helpful with large documents where partial retrieval can save on network overhead Both parameters take a comma separated list of fields or wildcard expressions. For example: ``` GET my-index-000001/_doc/0?_source_includes=*.id&_source_excludes=entities ``` If you only want to specify includes, you can use a shorter notation: ``` GET my-index-000001/_doc/0?_source=*.id ``` **Routing** If routing is used during indexing, the routing value also needs to be specified to retrieve a document. For example: ``` GET my-index-000001/_doc/2?routing=user1 ``` This request gets the document with ID 2, but it is routed based on the user. The document is not fetched if the correct routing is not specified. **Distributed** The GET operation is hashed into a specific shard ID. It is then redirected to one of the replicas within that shard ID and returns the result. The replicas are the primary shard and its replicas within that shard ID group. This means that the more replicas you have, the better your GET scaling will be. **Versioning support** You can use the `version` parameter to retrieve the document only if its current version is equal to the specified one. Internally, Elasticsearch has marked the old document as deleted and added an entirely new document. The old version of the document doesn't disappear immediately, although you won't be able to access it. Elasticsearch cleans up deleted documents in the background as you continue to index more data.

   * Get the cluster health. Get a report with the health status of an Elasticsearch cluster. The report contains a list of indicators that compose Elasticsearch functionality. Each indicator has a health status of: green, unknown, yellow or red. The indicator will provide an explanation and metadata describing the reason for its current health status. The cluster’s status is controlled by the worst indicator status. In the event that an indicator’s status is non-green, a list of impacts may be present in the indicator result which detail the functionalities that are negatively affected by the health issue. Each impact carries with it a severity level, an area of the system that is affected, and a simple description of the impact on the system. Some health indicators can determine the root cause of a health problem and prescribe a set of steps that can be performed in order to improve the health of the system. The root cause and remediation steps are encapsulated in a diagnosis. A diagnosis contains a cause detailing a root cause analysis, an action containing a brief description of the steps to take to fix the problem, the list of affected resources (if applicable), and a detailed step-by-step troubleshooting guide to fix the diagnosed problem. NOTE: The health indicators perform root cause analysis of non-green health statuses. This can be computationally expensive when called frequently. When setting up automated polling of the API for health status, set verbose to false to disable the more expensive analysis logic.

     * Migrate to data tiers routing. Switch the indices, ILM policies, and legacy, composable, and component templates from using custom node attributes and attribute-based allocation filters to using data tiers. Optionally, delete one legacy index template. Using node roles enables ILM to automatically move the indices between data tiers. Migrating away from custom node attributes routing can be manually performed. This API provides an automated way of performing three out of the four manual steps listed in the migration guide: 1. Stop setting the custom hot attribute on new indices. 1. Remove custom allocation settings from existing ILM policies. 1. Replace custom allocation settings from existing indices with the corresponding tier preference. ILM must be stopped before performing the migration. Use the stop ILM and get ILM status APIs to wait until the reported operation mode is `STOPPED`.

The `hits.total.relation` will always be `eq`, indicating an exact value.
