Reflection Summary

Use the Reflection API to retrieve a reflection summary that includes all raw and aggregation reflections for the Dremio instance.

Reflection summary objects are different from reflection objects. Reflection summaries do not include certain attributes that define the reflection, like the display, dimension, measure, sort, and partition attributes. Reflection summaries do include several attributes that do not appear in reflection objects, like datasetType, datasetPath, and counts and links for considered, matched, and chosen jobs.

Attributes of the `status` Object

configStatus String

Status of the reflection configuration. If OK, the reflection configuration is free of errors. If INVALID, the reflection configuration contains one or more errors.

Enum: OK, INVALID

Example: OK

refreshStatus String

Status of the reflection refresh.

GIVEN_UP: Dremio attempted to refresh the reflection multiple times, but each attempt has failed and Dremio will not make further attempts.

combinedStatus String

Status of the reflection based on a combination of configStatus, refreshStatus, and availabilityStatus.

CAN_ACCELERATE: The reflection is fully functional.
CAN_ACCELERATE_WITH_FAILURES: The most recent refresh failed to obtain a status, but Dremio still has a valid materialization.
CANNOT_ACCELERATE_INITIALIZING: The reflection is currently being loaded into the materialization cache. During this time, the reflection is unable to accelerate queries.
CANNOT_ACCELERATE_MANUAL: The reflection is unable to accelerate any queries, and the Never Refresh option is selected for the refresh policy.
CANNOT_ACCELERATE_SCHEDULED: The reflection is currently unable to accelerate any queries, but it has been scheduled for a refresh at a future time.
DISABLED: The reflection has been manually disabled.
EXPIRED: The reflection has expired and cannot be used.
FAILED: The attempt to refresh the reflection has failed, typically three times in a row. The reflection is still usable.
INVALID: The reflection is invalid because the underlying dataset has changed.
INCOMPLETE: Deprecated.
REFRESHING: The reflection is currently being refreshed.

Example: CAN_ACCELERATE

refreshMethod String

Enum: NONE, FULL, INCREMENTAL

Example: FULL

failureCount Integer

Number of times that an attempt to refresh the reflection failed.

Example: 0

lastFailureMessage String

The error message from the last failed reflection refresh. If the refresh of a reflection never fails or succeeds after a failure, this attribute does not appear.

lastDataFetchAt String

Date and time that the reflection data was last refreshed. In UTC format. If the reflection is running, failing, or disabled, the lastDataFetchAt value is 1969-12-31T23:59:59.999Z.

Example: 2023-01-13T19:05:03.532Z

expiresAt String

Available filter attributes:

reflectionType: RAW, AGGREGATION (array of string)
refreshStatus: GIVEN_UP, MANUAL, RUNNING, SCHEDULED, ON_DATA_CHANGES (array of string)
availabilityStatus: NONE, INCOMPLETE, EXPIRED, AVAILABLE (array of string)
configStatus: OK, INVALID (array of string)
enabledFlag: true, false (Boolean)
reflectionNameOrDatasetPath: full or partial reflection name or dataset path; case insensitive (string)
reflectionIds: IDs of reflections to retrieve (array of string); must be used alone, with no other filters or query parameters

orderBy Query String Optional

Example Request Without Query Parameters

curl -X GET 'https://api.dremio.cloud/v0/api/projects/1df71752-69b7-47d9-9e6c-990e6b194aa4/reflection-summary'

This endpoint supports query parameters that you can add to the request URL to include only specific types of reflections in the reflection summary, specify the maximum number of results to return, and sort the response to list reflections in ascending or descending order.

For example, to order the reflections within the summary in ascending order by reflectionName, add ?orderBy=reflectionName to the request URL. For descending order, add a - character before the attribute name: ?orderBy=-reflectionName.

In the same request, you can add the filter query parameter to retrieve only the raw reflections that are refreshed manually or by schedule, are enabled, and apply to datasets with samples.dremio.com in their paths. The JSON object for such a filter would look like this:

Example JSON Object for Filter

{
  "reflectionType": ["RAW"],
  "refreshStatus": ["MANUAL","SCHEDULED"],
  "enabledFlag": true,
  "reflectionNameOrDatasetPath": "samples.dremio.com"
}

However, to use the JSON object in the request URL, you must convert it to URL-encoded JSON, which looks like this:

Example JSON Object in URL-Encoded JSON

%7B%0A%20%20%22reflectionType%22%3A%20%5B%22RAW%22%5D%2C%0A%20%20%22refreshStatus%22%3A%20%5B%22MANUAL%22%2C%22SCHEDULED%22%5D%2C%0A%20%20%22enabledFlag%22%3A%20true%2C%0A%20%20%22reflectionNameOrDatasetPath%22%3A%20%22samples.dremio.com%22%0A%7D

Here is an example request URL that includes both the orderBy and filter query parameters:

Example Request With orderBy and filter Query Parameters

curl -X GET 'https://api.dremio.cloud/v0/api/projects/1df71752-69b7-47d9-9e6c-990e6b194aa4/reflection-summary?orderBy=reflectionName&filter=%7B%0A%20%20%22reflectionType%22%3A%20%5B%22RAW%22%5D%2C%0A%20%20%22refreshStatus%22%3A%20%5B%22MANUAL%22%2C%22SCHEDULED%22%5D%2C%0A%20%20%22enabledFlag%22%3A%20true%2C%0A%20%20%22reflectionNameOrDatasetPath%22%3A%20%22samples.dremio.com%22%0A%7D' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'

For this request, the reflection summary in the response will include only raw reflections that are refreshed manually or by schedule, are enabled, and apply to datasets with samples.dremio.com in their paths, and the reflections will be listed in ascending order by reflectionName.
