Cannot find AwaitableTriggerDagRunOperator anymore for Airflow [Python]

By -

I'm working on a python project using Airflow. In the project there is no requirements.txt file so I simply installed the latest version of the libraries by putting their name inside a requirement.txt file and I've been trying to make it work.

The import which is causing trouble is this one:

from airflow_common.operators.awaitable_trigger_dag_run_operator import (
    AwaitableTriggerDagRunOperator,
)

Looking online for AwaitableTriggerDagRunOperator I cannot find any documentation about this operator, the only result that comes up is this page where another person is using it and this person is importing it in the same way I am.

I guess that the project was developed with a very old version of Airflow and things have changed quite a bit. Here is the version that I have installed.

$ pip freeze | awk '/airflow/'
airflow-commons==0.0.67
apache-airflow==2.5.3
apache-airflow-providers-cncf-kubernetes==6.0.0
apache-airflow-providers-common-sql==1.4.0
apache-airflow-providers-ftp==3.3.1
apache-airflow-providers-http==4.3.0
apache-airflow-providers-imap==3.1.1
apache-airflow-providers-sqlite==3.3.1

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
