REST API

Repair the registry from storage

POST/v1alpha1/admin/registry/actions/repairregistry.repair

Registers every synced generation that storage holds and the registry does not name. The repair operation only adds entries: it keeps existing entries as stored and never deletes an index, a generation, or storage data. If the registry is absent, the repair writes it fresh. If the registry is corrupt, the repair replaces it with one rebuilt from storage.

When "promoteNewest": true, each index created by the repair answers for its highest-numbered generation. Hand-named generations are not selected. Indexes that are already registered keep what they answer for. When omitted or false, created indexes answer for nothing until a generation is promoted.

Storage of a deleted index or generation, which the audit reports with removedAt, is skipped until the sweep removes it. Naming it in "restore" takes the removal mark off and registers it like any other unregistered storage, which is how a delete is taken back within the grace period.

The write is conditional and rebuilds on top of concurrent registry changes. The answering node applies the repaired registry immediately; other nodes pick it up within EXOFIND_INDEXES_REFRESH_INTERVAL.

Served by whichever node receives the request and never forwarded. Answers only in object storage mode.

Body

RegistryRepairRequestOptional

How a repair should treat the indexes it creates, and which deleted indexes or generations it should bring back. The entire body is optional.

promoteNewestboolean
When true, each index created by the repair answers for its highest-numbered generation. Hand-named generations are not selected. Indexes that are already registered keep what they answer for. When false, a created index answers for nothing until a generation is promoted.
Default
false
restorestring[]
Names of deleted indexes (books) or generations (books@2) whose storage the sweep has not removed yet, to bring back. The repair registers what each one holds like any other unregistered storage, then takes the removal mark off it. A name whose storage holds no synced generation keeps its mark, so the sweep still removes it. A name without a mark changes nothing. Deleted storage is never registered without being named here.
Example
[
"books"
]

Responses

200
A summary of the changes made by the repair.
RegistryRepairResponse

Summary of the changes made by a repair. Every list empty means the registry already named everything storage holds, nothing was restored, and nothing was written.

createdIndexesstring[]
Index entries added to the registry, ordered by name.
addedGenerationsstring[]
Generations added to the registry, formatted as index@generation and ordered by name.
promotedstring[]
Generations made live by the repair, formatted as index@generation and ordered by name.
restoredstring[]
Deleted indexes and generations whose removal mark the repair took off, as index or index@generation, in the order the request named them. What they hold appears in the other lists.
400
An entry of restore is not a valid index or generation name.
ErrorResponse

The body of every failed request. Error codes use colon-separated namespaces such as index:field:name_invalid, are stable across API versions, and are never renamed or reused, so clients match on code rather than on message. See Errors.

codestring
Identifies the failure type. For validation failures, this is validation and the individual problems are listed in errors. For all other failures, this matches the code of the single entry in errors.
Example
"validation"
messagestring
Human-readable message for log output. Match on code rather than on message. When a validation failure contains one problem, this is that problem's message. When it contains several, it reads Request contains N errors.
Example
"Request contains 2 errors"
All problems found in the request. A validation failure reports every field with a problem, so a caller can fix them in one pass rather than one request at a time.
Example
{
"code": "index:field:primary_key:multiple_unsupported",
"message": "Field `id` is marked as a primary key and multiple, primary keys can not have multiple values",
"path": "id"
}
4 properties
codestring
The error code identifying this specific problem.
Example
"index:field:primary_key:multiple_unsupported"
messagestring
Human-readable description of this problem.
Example
"Field `id` is marked as a primary key and multiple, primary keys can not have multiple values"
pathstring
Location of the offending value in the request, such as fields.title or documents[1].nonexistent. Names join with ., one element of a list reads [n] counted from zero, and a key of a free-form map such as metadata goes in brackets and double quotes when it holds a dot or a bracket, as metadata["build.sha"]. A field inside an object field carries its own dotted path, so a path here reaches a field the same way a query does. Omitted when the problem applies to the request as a whole. See API conventions.
Example
"id"
argumentsmap of string
The values the message was rendered with, so a client can render a message of its own from the code.

<key>string
Error codes
index:name_invalid
An entry of `restore` is not a valid index or generation name.
401
The request carries no credential this node accepts. Absent, malformed, unknown and lapsed keys are all answered alike, so a refusal cannot be used to find out which keys exist. The response carries WWW-Authenticate: Bearer.

An API key sent as a bearer token, such as Authorization: Bearer exok_4ff6b760264c1918_ePQcdT1O9HSATZoXfDbT8hhHGsP9VpZH. A key carries grants that pair permissions with index patterns; the permission each endpoint needs is named beside it. Nodes running with EXOFIND_AUTH_MODE=none accept requests without a credential, and a node with EXOFIND_AUTH_ANONYMOUS_KEY set serves requests that carry none with the permissions of that key.
