Hello ,
I must create a temp table with 5 or more million records.
I need it for creating some reports, so I need to create indexes too.
My question is:
When total time for work will be smaller? :
1-st case: I create table and create indexes immediately before
filling data.
2-nd case: I create
I'd start with the indexes in place. 5+mil records will take quite some
time to index after the fact.

Filling the data data first and creating indexes after is faster, so you

From what I've read ( I think in the MySQL docs, might have been here in
the list), technically it will take less time
load. If that's the case it would probably cost

Heh..
I wasn't going by the docs when I responded... I had to reindex a 50+mil
