The issue being sqlite did not even remotely meet the criteria:

- it requires operating system,

- its memory footprint even in best case way larger than total memory available on the system,

- can't work in constant amount of memory (no dynamic allocations after application startup, compile-time verifiable stack usage)

- can't provably continue from any power cycle -- there is no guaranteed automated recovery method in case of unfortunate power cycle

- data storage overhead was unacceptable for the application
