I just read your blog on Spring Batch with Elasticsearch—thanks for sharing! It provided a clear and concise guide on integrating Spring Batch with Elasticsearch for data extraction and processing.

While exploring more, I found this resource on Using OpenSearch Java Client and Spring Boot for Search Integration: mobisoftinfotech.com/resources/blog/opensearch-ja… . It covers OpenSearch Java SDK, Spring Data OpenSearch, and best practices for performance tuning.

What are some key considerations for optimizing Spring Batch jobs when processing large Elasticsearch datasets? Also, how does Spring Batch compare with Apache NiFi for ETL workloads involving Elasticsearch? Looking forward to your insights. Great read!
