Please move the extended documentation to scripts/docs/*/ydb_cache.md
Huge pages in C++ code are considered harmful for new code

components::YdbCache -> ydb::CacheComponent
We don't use components:: namespace for new code, and duplicating "ydb" twice is also not the best naming

There is only 1 ydb component, but it has multiple databases

Add the new documentation page to index.md as a sublist item to main YDB page

Fix according to the position in index.md relative to other pages.
Also fix the footers in the neighbouring pages to point to the new ydb cache page

Please add a functional test. It shouldn't use any fancy features. Have a small, but realistic table. Add a handler that returns data from the cache. Check that the cache works. Check that the cache can get stale relatively to the data in the table, then call await service_client.invalidate_caches(cache_names=...) to update the cache and verify it
The test will also serve as a proof-of-concept that you've really got a working YDB cache. test/cache.cpp does not provide that guarantee
