Abstract: We introduce a general class of weighted spaces \(\mathcal{H}(\beta)\) of holomorphic functions in the unit disk \(\mathbb{D}\), which contains several classical spaces, such as Hardy space, Bergman space, Dirichlet space. We characterize boundedness of composition operators \(C_{\varphi}\) induced by affine and monomial symbols \(\varphi\) on these spaces \(\mathcal{H}(\beta)\). We also establish a sufficient condition under which the operator \(C_{\varphi}\) induced by the symbol \(\varphi\) with relatively compact image \(\varphi(\mathbb{D})\) in \(\mathbb{D}\) is bounded on \(\mathcal{H}(\beta)\). Note that in the setting of \(\mathcal{H}(\beta)\), the characterizations of boundedness of composition operators \(C_{\varphi}\) depend closely not only on functional properties of the symbols \(\varphi\) but also on the behavior of the weight sequence \(\beta\).
