– H2ONaCl Commented Dec 6, 2022 at one:37 yeah, that's good. I suppose my point is that folks could read "instantaneous" and by analogy with usual expectations of linear time, make the soar to assuming linearizability - exactly where if a person operation comes about just before another, you see the consequences in that order likewise. Which is not a assurance person atomic functions give when mixed.
The number of inputs over a transaction could also trigger bigger costs. If you send out some Bitcoin and It is damaged up into smaller items, these lesser pieces insert much more memory into the transaction.
They usually originate from modifications for the database, While it might seem more simple to widen a column and use it to things a number of values as opposed to adding a normalized linked table (which frequently breaks existing purposes).
