> We reached the limit of zk for storing LTR models. I want to avoid the
> usage of DefaultWrapperModel for as long as possible because we have
> deployed in an container orchestrator and this implementation can be
> really risky if you can not guarantee the presence of the model on
> disk all the time.
> So I want to use the managed model feature to upload some bigger
> models but zk is dying with OOM. What we noticed is that solr stores
> the models in a json indented file. By saving the models in compacted
> json our models will be 60% smaller.
