I would like to use lancedb in my fastapi in which multiple requests are received to search the ANN results. There are three options to handle this:

• A global lancedb connection
• A connection pool
• A new connection per request

Which one is the best practice? As for option 1 and 2, we need to make sure Lancedb is thread-safety. As for option 3, is it costly to init a connection?
