# Re-Indexing The mCollect Service

## Overview <a href="#overview" id="overview"></a>

We are using re-indexing to get all the data to the respective indexer. We have 2 steps for this. The first is to run the connector from the playground, which is followed by the legacyindexer service call from the indexer service, which internally calls the respective plain search service to get the data and send it to the respective indexer.

## **Pre-requisites**

* Access to kubectl of the environment targetted
* Postman scripts
* Plain search apis in the respective services

**mCollect/echallan-services reindexing steps**

* Configure the eChallan indexer with the configKey as `LEGACYINDEX` with the new topic name in the respective indexer yaml [file](https://github.com/egovernments/configs/blob/qa/egov-indexer/egov-echallan.yml)
* Connect to playground pod.
* Delete the kafka connector if already exists with the kafka connection, using below command through playground pod.

```
curl --location --request DELETE 'http://kafka-connect.kafka-cluster:8083/connectors/echallan-services-enriched-es-sink'
```

* Run the below kafka connector curl from playground pod:

```
curl --location --request POST 'http://kafka-connect.kafka-cluster:8083/connectors/' \
--header 'Cache-Control: no-cache' \
--header 'Content-Type: application/json' \
--header 'Postman-Token: 419e68ba-ffb9-4da9-86e1-7ad5a4c8d0b9' \
--data '{

    }
}'
```

* port forward to egov-indexer pod and run below curl throw postman

```
curl --location --request POST 'http://localhost:8055/egov-indexer/index-operations/_legacyindex' \
--header 'Content-Type: application/json' \

            ]
        }
    },
    "apiDetails": {
        "uri": "http://echallan-services.egov:8080/echallan-services/eChallan/v1/_plainsearch",

        "responseJsonPath": "$.challans"
    },
    "legacyIndexTopic": "echallan-legacyIndex",
    "tenantId": "pb"
}'
```

* Delete the kafka connection after all the data has been re-indexed by follwing below command through playground pod

```
curl --location --request DELETE 'http://kafka-connect.kafka-cluster:8083/connectors/echallan-services-enriched-es-sink'
```

* Alias firenoc-services-enriched as water-services through kibana server.

```
POST /_aliases 
{
  "actions": [
    {
      "add": {
        "index": "echallan-services-enriched",
        "alias": "echallan-services"
      }
    }
  ]
}
```

NOW your echallan-services index is updated with the eChallan/mCollect data.
