IMPORTING¶

Required arguments:¶

`iv_globalreplicationgroupid` `TYPE /AWS1/ECASTRING` `/AWS1/ECASTRING`¶

The name of the Global datastore

`iv_nodegroupcount` `TYPE /AWS1/ECAINTEGER` `/AWS1/ECAINTEGER`¶

The number of node groups (shards) that results from the modification of the shard configuration

`iv_applyimmediately` `TYPE /AWS1/ECABOOLEAN` `/AWS1/ECABOOLEAN`¶

Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true.

Optional arguments:¶

`it_globalnodegroupstoremove` `TYPE /AWS1/CL_ECAGLBNODEGRPIDLIST_W=>TT_GLOBALNODEGROUPIDLIST` `TT_GLOBALNODEGROUPIDLIST`¶

If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. GlobalNodeGroupsToRemove is a list of NodeGroupIds to remove from the cluster. ElastiCache will attempt to remove all node groups listed by GlobalNodeGroupsToRemove from the cluster.

`it_globalnodegroupstoretain` `TYPE /AWS1/CL_ECAGLBNODEGRPIDLIST_W=>TT_GLOBALNODEGROUPIDLIST` `TT_GLOBALNODEGROUPIDLIST`¶

If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. GlobalNodeGroupsToRetain is a list of NodeGroupIds to retain from the cluster. ElastiCache will attempt to retain all node groups listed by GlobalNodeGroupsToRetain from the cluster.

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_ecadecnodegrsinglbr01` `/AWS1/CL_ECADECNODEGRSINGLBR01`¶

Domain /AWS1/RT_ACCOUNT_ID

Primitive Type NUMC

Syntax Example¶

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.

DATA(lo_result) = lo_client->decnodegroupsinglbreplgroup(
  it_globalnodegroupstoremove = VALUE /aws1/cl_ecaglbnodegrpidlist_w=>tt_globalnodegroupidlist(
    ( new /aws1/cl_ecaglbnodegrpidlist_w( |string| ) )
  )
  it_globalnodegroupstoretain = VALUE /aws1/cl_ecaglbnodegrpidlist_w=>tt_globalnodegroupidlist(
    ( new /aws1/cl_ecaglbnodegrpidlist_w( |string| ) )
  )
  iv_applyimmediately = ABAP_TRUE
  iv_globalreplicationgroupid = |string|
  iv_nodegroupcount = 123
).

This is an example of reading all possible response values
