Memory Safe Cassandra Matches Consistency Task
This task compares entities and matches in the main storage.
This task compares two parts of the main storage: entities and matches in the background. It may resolve basic inconsistencies if found. If some entities are present in matches but not present in the entities data storage, this task removes these entities from the matches. If some entities are present in both parts but have different versions, this task rebuilds matches for such entities.
Note: Stop and Pause are supported. In case of Pause, the task restarts from the beginning.

|---|---|---|
tenantId
| Yes | ID of the tenant to compare matches and entities. |
entityType | No | The entity type to be checked (all types will be checked if this parameter is absent). |
maxResultsToStore | No | The task stores URIs of the entities, for which inconsistency was found, in its status. This parameter is required to prevent huge consumption of memory when a large number of entities with inconsistency are found. Default value: 100. |
compareVersions | No | If set to true, then the version of the objects in the entities and matches will also be compared.. Default is false. |
fixInconsistency | No | If set to true, the task will fix inconsistencies. Default is true. |
fixVersionConflicts | No |

taskPartsCount | No |
Specifies the maximum number of sub-tasks for distributed execution. The platform determines the optimal number based on performance limits. Default value is

Body (optional)
