# Restoring Search and Graph Indices from Local Database
|
|
|
|
If search or graph services go down or you have made changes to them that require reindexing, you can restore them from
|
|
the aspects stored in the local database.
|
|
|
|
When a new version of the aspect gets ingested, GMS initiates an MAE event for the aspect which is consumed to update
|
|
the search and graph indices. As such, we can fetch the latest version of each aspect in the local database and produce
|
|
MAE events corresponding to the aspects to restore the search and graph indices.
|
|
|
|
## Docker-compose
|
|
|
|
Run the following command from root to send MAE for each aspect in the Local DB.
|
|
|
|
```
|
|
./docker/datahub-upgrade/datahub-upgrade.sh -u RestoreIndices
|
|
```
|
|
|
|
If you need to clear the search and graph indices before restoring, add `-a clean` to the end of the command.
|
|
|
|
Refer to this [doc](../../docker/datahub-upgrade/README.md#environment-variables) on how to set environment variables
|
|
for your environment.
|
|
|
|
## Kubernetes
|
|
|
|
Run `kubectl get cronjobs` to see if the restoration job template has been deployed. If you see results like below, you
|
|
are good to go.
|
|
|
|
```
|
|
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE
|
|
datahub-datahub-cleanup-job-template * * * * * True 0 <none> 2d3h
|
|
datahub-datahub-restore-indices-job-template * * * * * True 0 <none> 2d3h
|
|
```
|
|
|
|
If not, deploy latest helm charts to use this functionality.
|
|
|
|
Once restore indices job template has been deployed, run the following command to start a job that restores indices.
|
|
|
|
```
|
|
kubectl create job --from=cronjob/datahub-datahub-restore-indices-job-template datahub-restore-indices-adhoc
|
|
```
|
|
|
|
Once the job completes, your indices will have been restored. |
