Re-Indexing The mCollect 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, 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
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
Connect to playground pod.
Delete the kafka connector if already exists with the kafka connection, using below command through playground pod.
Copy 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:
Copy 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' \
