Yandex.Mail's successful migration from Oracle to Postgres [pdf]

Am I missing something? How do you figure 10 man years = $500K ? Or is Yandex super stingy? DBAs and Developers worth their salt (who could pull off a multi-TB migration/etc without significant outage), would easily each go for $140K/yr minimum (so, 180-200K fully loaded with benefits and such).

Still though: your point is valid in that, Oracle RAC cluster licensing and support is serious bucks.

Yes, you're missing the fact that it's Russia, not SV.

Couple of years ago ruble's exchange rates dropped significantly (it was ~33RUR for USD, now it's 64-65 rubles).

Monthly salaries for a good engineer in Moscow are usually 100-200k rubles, or 1.2-2.4M rubles/year.

It's only $18-36k per year. Looks insane from typical californian HR's point of view, isn't it?

Taxes take additional ~50% (in Russia, employer pays all the taxes and payments to the pension fund), so $500k was a pretty good estimate.
