validation-overrides.xml is added to the root of an
application package
(i.e. next to services.xml)
to allow a deployment that otherwise fails to validate to proceed.
Validations which can be overridden in this way
are returned with a dash-separated validation-id preceding the validation message.
E.g. if the message is field-type-change: Changing the type of field 'foo' to 'bar' is not supported
the validation id is field-type-change
.
Validations protect against inadvertently corrupting a production instance. Overriding them may be useful e.g. if the application is not in production yet or if you think the consequences of inconsistencies or loss of the data in a particular field are fine.
Read more about schema changes in the schema reference.
Any number of allow
tags is permissible. Example:
An allow
tag disables a particular validation for a limited time.
It contains a single validation id, see list below.
allow
tags with unknown ids are ignored.
Attribute | Mandatory | Value |
---|---|---|
until | Yes | The last day this change is allowed, as a ISO-8601-format date in UTC, e.g. 2016-01-30.
Dates may at most be 30 days in the future, but should be as close to now as possible for safety,
while allowing time for review and propagation to all deployed zones.
allow -tags with dates in the past are ignored. |
comment | No | Text explaining the reason for the change to humans. |
ID | Required when... | Action needed or effect of change |
---|---|---|
indexing-change |
Changing what tokens are expected and stored in field indexes. | Requires reindexing of data. |
indexing-mode-change |
Changing the index mode (streaming, indexed, store-only) of documents. | Requires reindexing of data. |
field-type-change |
Field type changes. | Requires refeeding data. |
tensor-type-change |
Tensor type change. | |
resources-reduction |
Large reductions in node resources (> 50% of the current max total resources). | Might cause large load increase. |
content-type-removal |
Removal of a schema (causes deletion of all documents). | Causes loss of all documents in this schema. |
content-cluster-removal |
Removal (or id change) of content clusters. | Causes loss of all documents in the cluster. |
deployment-removal |
Removal of production zones from deployment.xml. | Causes removal of all clustersand data in the zones. |
global-document-change |
Changing global attribute for document types in content clusters. | Requires stopping all nodes, applying validation override and starting nodes again. |
global-endpoint-change |
Changing global endpoints. | |
zone-endpoint-change |
Changing zone (possibly private) endpoint settings. | |
redundancy-one |
The first deployment of an application with redundancy=1 requires a validation override. A redundancy of 2 is required for clusters in production otherwise |
|
paged-setting-removal |
Typically removed due to disadvantages described in doc. May cause content nodes to run out of memory. | More data will be loaded into memory, might cause OOM. |
certificate-removal |
Removing data plane certificates, typically when moving to new certificates. | Unable to accesss endpoint with removed certificates. |
