Fine grained control over various timeout and fallback parameters

Properties

edit

calm_wait_time (integer as int64): This timeout determines how long to give a cluster after it responds to API calls before performing actual operations on it. It defaults to 5s
cluster_reboot (string; allowed values: [forced]): Set to 'forced' to force a reboot as part of the upgrade plan. NOTES: (ie taking an existing plan and leaving it alone except for setting 'transient.plan_configuration.cluster_reboot': 'forced' will reboot the cluster)
extended_maintenance (boolean): If true (default false), does not clear the maintenance flag (which prevents its API from being accessed except by the constructor) on new instances added until after a snapshot has been restored, otherwise, the maintenance flag is cleared once the new instances successfully join the new cluster
max_snapshot_attempts (integer as int32): If taking a snapshot (ie unless 'skip_snapshots': true) then will retry on failure at most this number of times (default: 5)
move_allocators (array[AllocatorMoveRequest])
move_instances (array[InstanceMoveRequest])
move_only (boolean): If true (default: false) only move_instances and move_allocators instructions will be executed, all other changes will be ignored
override_failsafe (boolean): If false (the default) then the plan will fail out if it believes the requested sequence of operations can result in data loss - this flag will override some of these restraints
preferred_allocators (array[string]): List of allocators on which instances are placed if possible (if not possible/not specified then any available allocator with space is used)
reallocate_instances (boolean): If true (default: false) does not allow re-using any existing instances currently in the cluster, ie even unchanged instances will be re-created
skip_data_migration (boolean): If true (default: false) then the plan will not wait for data to be migrated from old instances to new instances before continuing the plan (potentially deleting the old instances and losing data)
skip_post_upgrade_steps (boolean): If false (the default), the cluster will run (currently) 2.x->5.x operations for any plan change ending with a 5.x cluster (eg apply a cluster license, ensure Monitoring is configured)
skip_snapshot (boolean): If true (default: false), does not take (or require) a successful snapshot to be taken before performing any potentially destructive changes to this cluster
skip_upgrade_checker (boolean): If false, the cluster is checked for issues that should be resolved before migration (eg contains old Lucene segments), if true this is bypassed
timeout (integer as int64): The total timeout in seconds after which the plan is cancelled even if it is not complete. Defaults to 4x the max memory capacity per node (in MB). NOTES: (eg a 3 zone cluster with 2 nodes of 2048 each would have a timeout of 4*2048=8192 seconds)
