Do you mean ADBC? In general, yes, a Connection should be used from a single thread at-a-time in database APIs (ODBC/JDBC/ADBC...).
That is the case because a Connection represents a "session". Each statement can potentially change the internal session state that connection represents. If you have multiple threads alternating access to a connection, the end result becomes non-deterministic. -- Felipe On Mon, Jan 26, 2026 at 10:47 PM Pedro Matias <[email protected]> wrote: > Hello, > > What thread-safety guarantees do we intend to provide for the JDBC driver? > > My understanding is that, for example, a Connection is only safe to use > from a single thread.
