elastic VS lens

i am trying to generate the following query using github.com/olivere/elastic/v7

I think that https://olivere.github.io/elastic/ is a lot better as an API client

For Go available two good libraries for elasticsearch, the official Elasticsearch client and another one from community olivere elastic, both is good, but at this moment only the official client supports 8 version of elasticsearch and for serious production think it's the choice.

You are using the Query DSL, which is documented here, and has examples for boolean combination queries, so if you want it built up in a more strongly-typed fashion, check the documentation for it: https://github.com/olivere/elastic/wiki/QueryDSL

ElasticSearch repository implementation uses go-elasticsearch official library, another good one is olivere elastic but here it's not support 8 version which used for this project.

In this project we have microservice working with EventStoreDB using oficial go client, for [projections (https://zimarev.com/blog/event-sourcing/projections/) used MongoDB and Elasticsearch for search, and communicate by gRPC and REST. Did not implement here any interesting business logic and didn't cover tests, because don't have enough time, the events list is very simple: create a new order, update shopping cart, pay, submit, cancel, change the delivery address, complete order, and of course in real-world better use more concrete and meaningfully events, but the target here is to show the idea and how it works. Event Sourcing can be implemented in different ways, used here EventStoreDB, but we can do it with PostgreSQL and Kafka for example. After trying both approaches, found EventStoreDB is a better solution because all required features are implemented out of the box, it is optimized and really very good engineers developing it.

Relevant Discussion from the maintainer

I have only used the olivere library and I think it is as good as a Go library gets.

Lens

Generally I felt as if I was diving in the deepest of waters without the correct equipement and that was horrifying. Unfortunately to me, I had to dive even deeper before getting equiped with tools like ArgoCD, and k8slens. I had to start working with... HELM.

Indeed you can, with several "paid" features removed, like log tailing and pod shells. They deliberately hobbled the product. If you want to use Lens, my advice is pay for the supported version.

yes I know there is lens, but it does not allow me to see logs of multiple pods at same time and what is even more important it is not friendly for ephemeral clusters - in my case with help of kind I am recreating whole cluster each time from scratch

Let's wait for few seconds for the pods to become green, I am using Lens, it's awesome btw.

You probably don't need Rancher unless you need a GUI or manage multiple clusters, Lens or k9s might be a better fit for your use case.

`openlens` is now preferred over `Lens`, it has everything you need and none of the fluff that Lens wants to charge you for.
