7.17.1

Client

• Fixed serialization of the routing parameter for the BulkIndexerItem routing property.

8.0.0

Client

• The client now uses elastic-transport-go dependency which lives in its own repository.
• With the knewly extracted transport, the retryOnTimeout has been replaced with a retryOnError callback. This allows to select more finely which error should be retried by the client.
• BulkIndexerItem Body field is now an io.ReadSeeker allowing reread without increasing memory consumption.
• BulkIndexerItem know correctly uses the routing property instead of the deprecated _routing.

API

• API is generated from the Elasticsearch 8.0.0 specification.

7.17.0

Client

• Fixed a race condition on metrics in transport #397, thanks @mainliufeng !
• The client will now return an error if a required arguments is passed as a nil value. #201
• API is compatible with Elasticsearch 7.17.0

8.0.0-alpha

Client

Elastic Transport

• This is the first release using the all new elastictransport which now lives in the elastic-transport-go repository. The goal is to allow for reuse between this and future Go clients.

API

• Changed the Body parameter for BulkIndexerItem in favor of io.ReadSeeker to lower memory consumption when using the esutil.BulkIndexer.
• Replaced the Config option RetryOnTimeout in favor of a new RetryOnError function which allows to dynamically chose what error should be retried.

7.16.0

Client

• Adds versioning and routing options to the BulkIndexer. Thanks to @mehran-prs and @munkyboy !

• Adds CA fingerprinting. You can configure the client to only trust certificates that are signed by a specific CA certificate (CA certificate pinning) by providing a ca_fingerprint option. This will verify that the fingerprint of the CA certificate that has signed the certificate of the server matches the supplied value:

    elasticsearch.NewClient(Config{
        Addresses:              []string{"https://elastic:changeme@localhost:9200"},
        CertificateFingerprint: "A6FB224A4386..."
    })

7.14.0

Client

Starting in v7.14.0 the client performs a required product check before the first API call is executed. This product check allows the client to establish that it’s communicating with a supported Elasticsearch cluster.

The product check requires a single HTTP request to the info API. In most cases this request will succeed quickly and then no further product check HTTP requests will be sent.
