How can I query any table/database? Is there syntax/format for entering in server, port, user, password, database, etc.?
do you refer the OpenSearch Search Engine as Database or do you mean a Database like MySQL or MariaDB?
Could you please describe what’s your Issue or what you want to build so we can help you by that?
if you want something that collects your data in databases and tokenizes them in opensearch, I recommend using logstash. and very simple to use. Use for mysql, oracle, db2, mongo and postgree
