CLUSTER command for Firebird?

Question

PostgreSQL has a command CLUSTERthat can defragment data on demand, and not automatically, which kills write speed.

Can Firebird CLUSTEROn Demand?

(I can't find it in the docs, and google searches look short. Pretty cars tho)

Answer 1

There is no such command for Firebird (this is also the reason why you cannot find it). Firebird does not have clustered indexes and does not have the ability to "fake" them, as PostgreSQL does.
