Is this a reasonable tool to manage problems like: I've got a stream of json in one schema; I want to make ETL for this to write it out to elasticsearch, S3 (in a specific different schema) and postgres targets, using a mixture of "bespoke python", vector, and logstash. Should I use this or should I roll my own goo using ERB or mustache or similar? Or should I quit and go work some place that's using gRPC?
