We don't have a lot of in-depth documentation, partly because the
implementation details change frequently.

Have you read the Impala paper?
http://cidrdb.org/cidr2015/Papers/CIDR15_Paper28.pdf
(here's a summary:
https://blog.acolyer.org/2015/02/05/impala-a-modern-open-source-sql-engine-for-hadoop/
)

There's also an old paper on code generation:
https://pdfs.semanticscholar.org/bac4/169d6b6f713c76271b5ccf3d45293351f785.pdf

But the very best thing to read is the source code...
