Modifying Configurations

Currently, only Ray and SQL warm-up resources support configuration modifications. Other service scenarios utilize pay-per-use billing and do not involve order changes and billing mode changes.

Table 1 details the impact of modifying Ray or SQL warm-up resource sizes on billing.
