Elastic has modified the official Python client for its Elasticsearch database not to work with forked versions, and closed the GitHub issue to comments.
Elasticsearch is a database manager and analytics engine, often used for log analytics. The elasticsearch-py client has over 202,000 downloads and is described as the “official low-level client for Elasticsearch. Its goal is to provide common ground for all Elasticsearch-related code in Python; because of this it tries to be opinion-free and very extendable.” It is also used as a library by Elasticsearch DSL, a high-level library for running Elasticsearch queries.
Elasticsearch was an open-source product, but in January changed its licensing in response to what the company saw as unfair usage by public cloud platforms, AWS in particular. AWS forked Elasticsearch, before the licence change, to create the Open Distro for Elasticsearch, which later evolved into OpenSearch, which had its 1.0 release last month. Casualties of this corporate battle include open-source developers who contributed to Elasticsearch but now feel let down.
