Cassandra ES Consistency Task
Compares entities in the main and search storage areas.
This task compares entities between the main and search storage areas and resolves basic inconsistencies if found. If some entities are present in the search but not present in the main data storage, this task removes these entities from the search storages. If some entities are present in the main storage but not present in search, task tries to reindex such entities.
Note: Stop and Pause are supported. In case of Pause, the task restarts from the beginning.
Requests:
- Tenant admin role is required:
POST {ApplicationURL}/esCassandraConsistencyCheck - Tenant admin role is required:
POST {ApplicationURL}/api/{tenantId}/esCassandraConsistencyCheck&fast=true
Note: The
fast=true option is deprecated. Therefore, use the MemorySafeCassandraEsConsistency task instead.Body
If provided, this will process the objects specified in the JSON array.

]| Parameter | Required | Description |
|---|---|---|
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: 1000. |
compareVersions | No | If set to true, then the version of the objects in the main and search storages will also be compared. Default is false. |
fixInconsistency | No | If set to true, the task will fix inconsistencies. Default is true. |
restoreTILs | No | If this parameter is set to true, the task will add TIL column for entities (losers) for which it is missed. By default, this is set to false. |
fixVersionConflicts | No |
If the parameter is set to true, then the task will reindex entities with version conflicts in ES. Default is |
| distributed | No |
If set to
true, the task runs in distributed mode. Default value is false. For more information, see Distributed mode. |
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
2. Note: This parameter is only applicable when distributed=true. Otherwise, it s ignored. |
largeVersionThreshold | No | The version threshold that is used to flag objects having a large version. Any object whose version is over this threshold is reported in the objectsAboveVersionThreshold field. The total number of objects that have a version above this threshold value is reported in the totalObjectsAboveVersionThreshold field. The default value for this field is 2^60. |
