Enclosing class:

AdminRemoveRanksRequest

public static final class AdminRemoveRanksRequest.Options
extends Object

Optional parameters.

• REBALANCE_SHARDED_DATA: If true, sharded data will be rebalanced approximately equally across the cluster. Note that for clusters with large amounts of sharded data, 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: If true, unsharded data (a.k.a. randomly-sharded) will be rebalanced approximately equally across the cluster. Note that for clusters with large amounts of unsharded data, 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 is moved at a time during rebalance. A higher aggressiveness will complete the rebalance faster. A lower aggressiveness will take longer but allow for better interleaving between the rebalance and other queries. Valid values are constants from 1 (lowest) to 10 (highest). The default value is '10'.

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