Connectivity & transports

Default server port

AthenaDB Server listens on TCP port 1440 by default (configurable), with TLS on the secure path.

Local IPC

• Windows: named pipes
• Unix-family: Unix domain sockets (macOS, Linux, FreeBSD, Solaris)

Local and remote transports share the product connectivity story; OS identity → database principal reconciliation on every path is still completing.

HTTP/2 & mTLS

HTTP/2 mTLS transport pieces exist in the engine; product polish and verified cross-platform evidence remain Early Access work.

ODBC

ODBC is tracked in the engine registry and is not a GA / Available-now claim. Prefer the C ABI and SQLite-compatible C API for Early Access integration. See C ABI & SDKs.
