Query performance issues can stem from inefficient SQL queries, lack of indexes, or large result sets. It is important to optimize the queries by using appropriate indexes and limiting the amount of data retrieved.

Future of JDBC

JDBC continues to evolve alongside advancements in database technology and Java development. Recent developments include support for new features such as distributed transactions, connection pooling, and enhanced security mechanisms.
With the rise of cloud computing and big data technologies, JDBC is expected to play a crucial role in enabling Java applications to interact with modern data storage solutions, such as NoSQL databases and data lakes.
