Asking for help，BulkRequest operation , which caused many threads to be blocked

Conductor version: 2.19.0

Recently, I found that there was a serious synchronization lock problem during ES operation, which caused many threads to be blocked

workflow.elasticsearch.index.batchSize=10

ElasticSearchRestDAOV6.java

    private synchronized void indexBulkRequest(String docType) {
       .....
    }

For example:

• Updateworkflow of system task worker - * blocked by indexBulkRequest method
• Workflowsweeper blocked by indexBulkRequest method
• Startworkflow blocked by indexBulkRequest 26603.stack.zip method

Do you have any plans to improve this situation? Thanks.

Also, you can try having a higher queue size.

Hi @manheiba . From the stack trace looks like you are using sync configuration but environment is high throughput. Can you please try enable async indexing
