Before the client asks for the next twenty, another transaction inserts a row near the front of that order. The data set has changed, but the client still expects page two to continue from the point page one reached.</p> <p>That expectation exposes the main difference between offset pagination and keyset pagination. An offset identifies a position in a particular query result. A keyset cursor identifies an ordering boundary. Under concurrent writes, those are not equivalent references.</p>
