Reference

dynamo.nixl_connect.RdmaMetadata#

A Pydantic type intended to provide JSON serialized RDMA metadata about a ReadableOperation or WritableOperation object. RDMA metadata contains detailed information about a worker process and how to access memory descriptors registered with it. This data is required to perform data transfers using the NIXL based RDMA subsystem.

Warning

RDMA metadata contains a worker’s address as well as security keys to access specific registered memory descriptors. 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.
