PostgreSQL has a CLUSTER command that can defrag the data on-demand rather than automatically which kills write speed.
Can Firebird CLUSTER on demand?
(I can't find it in the docs, and google searches come up well short. Pretty cars tho)
回答1:
There is no such command for Firebird (which is also the reason you can't find it). Firebird doesn't have clustered indexes, and doesn't have a way to 'fake' them like PostgreSQL does.
