Note

This parameter is available starting from ODP 4.3.1.

Description

rpc_async_pull_batch_max_size specifies the size of the partition address for asynchronous batch pull. Before using this parameter, make sure that the value of rpc_enable_async_pull_batch_tablets is set to True, which enables the asynchronous batch pull of tablet IDs.

Attributes

Attribute
Description
Parameter type Integer
Default value 10
Value range [2, 50]
Effective only after ODP restart Yes

Examples

  1. Enable the asynchronous batch pull of tablet IDs.

    obclient> alter proxyconfig set rpc_enable_async_pull_batch_tablets='True';
    
  2. Set the size of the partition address for asynchronous batch pull to 20.

    obclient> alter proxyconfig set rpc_async_pull_batch_max_size=20;
