Frequently Asked Questions
Should I focus on platform or analytics engineering?
Both are valuable paths. Platform is infrastructure-focused, analytics engineering is transformation-focused. Choose what excites you.
Is data mesh just hype?
The concepts are real: domain ownership, self-serve, data products. Whether you call it 'mesh' matters less than understanding decentralized data architecture.
