databases and time-series data. It supports operations such as connecting to the database, creating, querying, updating, and deleting data, as well as batch insertion and querying of time-series data.</p><p><strong>Note:</strong> The current JDBC implementation is designed primarily for integration with third-party tools. High-performance writing <strong>may not be achieved</strong> when using JDBC for insert operations. For Java applications, it is recommended to use the <strong>JAVA Native API</strong> for optimal performance.</p><h2 id="_1-prerequisites" tabindex="-1"><a class="header-anchor" href="#_1-prerequisites"><span>1.
