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

bool as_policy_batch::concurrent |
Determine if batch commands to each server are run in parallel threads.
Values:
Definition at line 888 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 933 of file as_policy.h.
uint32_t as_policy_batch::retry |
Maximum number of retries when a transaction fails due to a network error. Used by synchronous commands only. Default: 1
Definition at line 842 of file as_policy.h.
bool as_policy_batch::retry_on_timeout |
Should the client retry a command if the timeout is reached. Used by synchronous commands only.
Values:
retry
. Default: false
Definition at line 868 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 926 of file as_policy.h.
uint32_t as_policy_batch::sleep_between_retries |
Milliseconds to sleep between retries. Used by synchronous commands only. Default: 0 (do not sleep)
Definition at line 849 of file as_policy.h.
uint32_t as_policy_batch::timeout |
Maximum time in milliseconds to wait for the operation to complete.
Definition at line 835 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)
