Trending @Infosys; Career Advice on Java Backend skillset

Hi folks

Is it really worth continuing in java based roles(Java, Spring boot, MS) or can we change career path to big data engineering roles(using ETL tools, pyspark, Databricks).

I feel there is heavy competition in coding rounds( like everyone doing DSA and mastering it) if we want offers from reputed product based companies.

Does transitioning into (Java + Big Data Engineer) opens unique opportunities from product companies or do I need to continue Java + Cloud path.

Any experienced folks who can shed some tips.Thanks in advance

PS : Mention the career paths where we can fetch some high CTCs or careers in foreign (long term)
