bool as_policy_batch::allow_inline |
Allow batch to be processed immediately in the server's receiving thread when the server deems it to be appropriate. If false, the batch will always be processed in separate transaction threads. This field is only relevant for the new batch index protocol.
For batch exists or batch reads of smaller sized records (<= 1K per record), inline processing will be significantly faster on "in memory" namespaces. The server disables inline processing on disk based namespaces regardless of this policy field.
Inline processing can introduce the possibility of unfairness because the server can process the entire batch before moving onto the next command. Default: true

as_policy_consistency_level as_policy_batch::consistency_level |
Specifies the number of replicas consulted when reading for the desired consistency guarantee.
Definition at line 707 of file as_policy.h.
bool as_policy_batch::deserialize |
Should raw bytes be deserialized to as_list or as_map. Set to false for backup programs that just need access to raw bytes. Default: true
Definition at line 772 of file as_policy.h.
bool as_policy_batch::linearize_read |
Force reads to be linearized for server namespaces that support CP mode. Default: false
Definition at line 778 of file as_policy.h.
bool as_policy_batch::send_set_name |
Send set name field to server for every key in the batch for batch index protocol. This is only necessary when authentication is enabled and security roles are defined on a per set basis. Default: false
Definition at line 765 of file as_policy.h.
bool as_policy_batch::use_batch_direct |
Use old batch direct protocol where batch reads are handled by direct low-level batch server database routines. The batch direct protocol can be faster when there is a single namespace, but there is one important drawback. The batch direct protocol will not proxy to a different server node when the mapped node has migrated a record to another node (resulting in not found record).
This can happen after a node has been added/removed from the cluster and there is a lag between records being migrated and client partition map update (once per second).
The new batch index protocol will perform this record proxy when necessary. Default: false (use new batch index protocol if server supports it)
