Description

There are various JDBC issues that were detected through Tableau integration tests. This issue details those issues to be fixed for 0.9.0 release.

- The default maximum limit on records is added to SQL queries without a defined limit, which causes errors to be returned for some queries.
- Various timeout issues were detected in the async HTTP client requests to the Pinot broker.

Research direction

Start with the Tableau integration tests and the JDBC client paths involved in SQL query limits and async HTTP requests to the Pinot broker. Reproduce a query without a defined limit and the reported timeout cases; done means both issue categories are fixed and the integration tests pass.
