New data analyst. Company is moving to a NoSQL db for data analytics

This is gonna be my first role as a Data analyst transitioning from a Project Lead/BA role and a commerce background. I can say naman I have a good foundation with SQL, Data viz software building on my business domain experience but the startup I'm part of is going full hypergrowth phase and have made moves to migrate our database into a NoSQL style DB (think Mongo, Cassandra, Elasticsearch, etc).

Too be honest, learning curve talaga siya and our whole team is super nangangapa coming from our old stack of BigQuery and GDS. When I search online, there isn't much resources regarding the topic of data analyst and NoSQL so I have no idea how I can chart my career from here and how to go about these things. Looking for some career guidance from veteran DAs who are in the same company setup. This my first time in this more technical role so I am determined to learn as much as I can (free time ko is all upskilling) and I'm really hoping this experience can set me up for the future.
