Settings

`OPENSEARCH_DSL`

Required

OPENSEARCH_DSL is used to configure the connections to opensearch. It must at least define a 'default' connection with a given 'hosts':

OPENSEARCH_DSL = {
    'default': {
        'hosts': 'localhost:9200'
    }
}

OPENSEARCH_DSL is passed to opensearchpy.connection.connections.configure() .

`OPENSEARCH_DSL_INDEX_SETTINGS`

Default: {}

Additional options passed to the opensearch-py Index settings (like number_of_replicas or number_of_shards). See Opensearch's index settings for more information.

`OPENSEARCH_DSL_AUTO_REFRESH`

Default: False

Set to True to force an index refresh with update.

`OPENSEARCH_DSL_PARALLEL`

Default: False

Run indexing in parallel using OpenSearch's parallel_bulk() method. Note that some databases (e.g. SQLite) do not play well with this option.

`OPENSEARCH_DSL_QUERYSET_PAGINATION`

Default: 4096

Size of the chunk used when indexing data. Can be overridden by setting queryset_pagination inside Document' s Django subclass.

`OPENSEARCH_DSL_AUTOSYNC`

Default: True

Set to False to globally disable auto-syncing.

See Autosync for more information.

The autosync operations can be customized using OPENSEARCH_DSL_SIGNAL_PROCESSOR setting.

`OPENSEARCH_DSL_SIGNAL_PROCESSOR`

Default: django_opensearch_dsl.signals.RealTimeSignalProcessor.

This (optional) setting controls what SignalProcessor class is used to handle Django’s signals and keep the indices up-to-date. While some builtin choices are provided, you can also define your own by subclassing django_opensearch_dsl.signals.BaseSignalProcessor.

Builtin choices are:

django_opensearch_dsl.signals.RealTimeSignalProcessor

Operations are processed synchronously as soon as the signal is emitted.

django_opensearch_dsl.signals.CelerySignalProcessor

Uses Celery to process the operations asynchronously.

`OPENSEARCH_DSL_SIGNAL_PROCESSOR_SERIALIZER_CLASS`

Default: django.core.serializers.json.DjangoJSONEncoder.

When using asynchronous signal processor such as CelerySignalProcessor, the instance will probably be deleted from the database by the time the operation is processed. Since django-opensearch-dsl need a relies on the database to do most of its operation, the instance will be serialized by the signal and deserialized by the processor to keep a valid instance.

This serialization process can be customized using this setting. See Django's serialization documentation for more information.

`OPENSEARCH_DSL_SIGNAL_PROCESSOR_DESERIALIZER_CLASS`

Default: OPENSEARCH_DSL_SIGNAL_PROCESSOR_SERIALIZER_CLASS.

Use by the processor to deserialize the data serialized by the signal. See OPENSEARCH_DSL_SIGNAL_PROCESSOR_SERIALIZER_CLASS for more information.
