[erlang-questions] How would you implement TTL for ETS based cache?

[Max Bourinov]

Hi Erlangers,

How would you implement TTL with callback for ETS based cache?

I want when TTL expires callback is triggered and cached value goes to DB.

For key I use 32 byte long binary(), value is not bigger than 8 KB.

Any suggestions?

p.s. elang:send_after/3 is a most brutal approach, but how would it be when
cache is under load?

Best regards,
Max
