Enclosing class:

AdminRemoveRanksRequest

public static final class AdminRemoveRanksRequest.Options
extends Object

Optional parameters.

• REBALANCE_SHARDED_DATA: When true, data with primary keys or shard keys will be rebalanced to other ranks prior to rank removal. Note that for big clusters, this data transfer could be time consuming and result in delayed query responses. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.
• REBALANCE_UNSHARDED_DATA: When true, unsharded data (data without primary keys and without shard keys) will be rebalanced to other ranks prior to rank removal. Note that for big clusters, this data transfer could be time consuming and result in delayed query responses. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.
• AGGRESSIVENESS: Influences how much data to send per rebalance round, during the rebalance portion of removing ranks. A higher aggressiveness setting will complete the rebalance faster. A lower aggressiveness setting will take longer, but allow for better interleaving between the rebalance and other queries. Allowed values are 1 through 10. The default value is '1'.

The default value is an empty Map. A set of string constants for the parameter options.
