I am very new to Talend Data Integration. I am investigating tools to accomplish a one-time(big-bang) migration from AWS MySQL to OpenSearch. As I understand it is possible to do it with Talend.
There are 2 important points to mention here: It is a big data and we need to join tables to a single Elasticsearch index. (For example: Master table is Order, child tables are OrderDetails and OrderLines)
Is it possible to accomplish this migration with Talend? Does it support parallel running as well?
