Handshake request that must be sent to server first.

Fields

topic: String

Path of topic to write to.

message_group_id: String

message group identifier of client data stream a.k.a. sourceId.

session_meta: HashMap<String, String>

Some user metadata attached to this write session.

partition_group_id: i64

Partition group to write to. Zero means any group.

max_supported_block_format_version: i64

session_id: String

connection_attempt: i64

0 for first init message and incremental value for connect retries. Used for server logging.

connection_meta: Vec<u8>

Opaque blob. Take last one from previous connect.

preferred_cluster: String

Optinal preferred cluster name. Sever will close session If preferred cluster is not server cluster and preferred cluster is enabled after delay TPQConfig::CloseClientSessionWithEnabledRemotePreferredClusterDelaySec

idle_timeout_ms: i64

Sanity check option. When no writing activity is done in idle_timeout_sec seconds, then session will be destroyed. Zero means infinity.
