## What feature or improvement would you like to see?
Every `AdbcDatabase.connect()` in the Java Flight SQL driver pays full
channel setup (TCP + TLS + auth handshake) — costly for request-scoped usage
like web services and query gateways. Go, Python, and Rust users get pooling
from ecosystem
layers (`database/sql`, SQLAlchemy, r2d2), but nothing in the Java
ecosystem can pool an `AdbcConnection` since it isn't a `java.sql.Connection`.
Would an opt-in (default-off, feature-flagged) connection pool for Java
ADBC be welcome? If there's interest, I'll follow up with a design proposal and
implementation.
