How Ozone manages write operations

The client requests a block from the Ozone Manager (OM) to write a key. OM returns the Block ID and the corresponding DataNodes for the client to write data.

1. The client requests a block from OM to write a key. The request includes the key, the data to write, the pipeline type, and the replication count.
2. OM finds the blocks that match the request and returns them to the client.
3. The client connects to the DataNodes associated with the returned Block ID and writes chunks of data.
4. After writing the chunks of data, the client informs OM to finalize the key.
5. OM records the associated key information.
