Legacy/Re-Indexing the Water & Sewerage Service

Overview

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. This is followed by a legacy indexer 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

Configuration Steps

We have two services for water and sewerage

water-services
sewerage-services

Water-services Reindexing Steps

Connect to playground pod.
Delete the Kafka connector if already exists with the Kafka connection, using the below command through playground pod.

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

Run 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.

Delete the Kafka connection after all the data has been re-indexed by following the below command through the playground pod.

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

Alias water-services-enriched as water-services through the Kibana server.

POST /_aliases 
{
  "actions": [
    {
      "add": {
        "index": "water-services-enriched",
        "alias": "water-services"
