Class DeleteRequest

java.lang.Object

public class DeleteRequest extends RequestBase
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.

    • id

      public final String id()
      Required - A unique identifier for the document.

      API name: id

    • ifPrimaryTerm

      @Nullable public final Long ifPrimaryTerm()
      Only perform the operation if the document has this primary term.

      API name: if_primary_term

    • ifSeqNo

      @Nullable public final Long ifSeqNo()
      Only perform the operation if the document has this sequence number.

      API name: if_seq_no

    • index

      public final String index()
      Required - The name of the target index.

      API name: index

    • refresh

      @Nullable public final Refresh refresh()
      If true, Elasticsearch refreshes the affected shards to make this operation visible to search. If wait_for, it waits for a refresh to make this operation visible to search. If false, it does nothing with refreshes.

      API name: refresh

    • routing

      @Nullable public final String routing()
      A custom value used to route operations to a specific shard.

      API name: routing

    • timeout

      @Nullable public final Time timeout()
      The period to wait for active shards.

      This parameter is useful for situations where the primary shard assigned to perform the delete operation might not be available when the delete operation runs. Some reasons for this might be that the primary shard is currently recovering from a store or undergoing relocation. By default, the delete operation will wait on the primary shard to become available for up to 1 minute before failing and responding with an error.

      API name: timeout

    • version

      @Nullable public final Long version()
      An explicit version number for concurrency control. It must match the current version of the document for the request to succeed.

      API name: version

    • versionType

      @Nullable public final VersionType versionType()
      The version type.

      API name: version_type

    • waitForActiveShards

      @Nullable public final WaitForActiveShards waitForActiveShards()
      The minimum number of shard copies that must be active before proceeding with the operation. You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The default value of 1 means it waits for each primary shard to be active.

      API name: wait_for_active_shards
