dynamo.nixl_connect.RdmaMetadata#
A Pydantic type intended to provide JSON serialized NIXL metadata about a ReadableOperation or WritableOperation object. NIXL metadata contains detailed information about a worker process and how to access memory regions registered with the corresponding agent. This data is required to perform data transfers using the NIXL-based I/O subsystem.
Warning
NIXL metadata contains information to connect corresponding backends across agents, as well as identification keys to access specific registered memory regions. This data provides direct memory access between workers, and should be considered sensitive and therefore handled accordingly.
Use the respective class’s .metadata() method to generate an RdmaMetadata object for an operation.
Tip
Classes using RdmaMetadata objects must be paired correctly. ReadableOperation with ReadOperation, and WritableOperation with WriteOperation. Incorrect pairing will result in an error being raised.
