Re: NXT :: descendant of Bitcoin - Updated Information

Question: Is it possible to re-use the nxt_db directory when upgrading from 0.7.4 to 0.7.5 without downloading the whole blockchain again?

Yes, it is designed to be possible to upgrade without having to delete the nxt_db directory, that's the reason I bother with applying those SQL statements.

If too slow for Raspberries, do whichever is faster, upgrade or download from scratch.

Did I manage to improve the Raspberry performance with the last release?

What exactly do you mean by performance?

1) startup is slow as always. Especially these migrations

2) running is as good as always. Does not go above 5%.

3) RAM consumption is 1% lower.

yes, which is why having the option of using the nxt_db is quite helpful

Why is that? Or maybe, I didn't understand what you mean.

when you update, you just dump the old nxt_db directory into the nxt_db in the unzip directory of the new version, and the blockchain won't be downloaded -just as with before, when you could just dump the blocks.nrs and transactions.nrs into the new version.
only then it would crash very often, and now with sql it hopefully won't.

At least that's what I understand from it.
