Overview:

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

Prerequisites:

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

We have mainly 3 indexes in mGramseva for Re-indexing.

Water-services
Echallan-services
dss-collection_v2

Stpes to follow for re-indexing:

Delete the kafka connector if already exists with the kafka connection, using below command to delete connector
Code Block
curl -X DELETE http://kafka-connect.mgramseva:8083/connectors/water-services-enriched-es-sink
