Hi team , Need help in client creation in multi thread environment ,because we are trying singleton design pattern with lazy instantiation for weaviate . In this, while client establishment, another threads start executing and causes error  
“No Attribute client”. I just need two things. first , the client instantiation is synchronous or asynchronous, if this is asynchronous then I can easily using async await. Second, if not then how to resolve this??

Hi!

Sorry for the delay here!

There are some discussion going on here:

> <https://github.com/weaviate/weaviate-python-client/issues/88>

Also, is good to mention that a new python client is being developed. Check more information about it: [Shape the Future - Try Our New Python Client API | Weaviate - vector database](https://weaviate.io/blog/collections-python-client-preview)

Thanks!
