Abstract: In accordance with the described techniques, a configuration update is received changing configuration parameters of a data stream processing application from a source configuration to a target configuration. In addition, the configuration update specifies incremental update parameters indicating how different partitions of the data stream processing application are to be incrementally updated. The computing device is configured to incrementally update the data stream processing application. During a time interval indicated by the incremental update parameters, for instance, the target configuration is applied to a first partition, and the source configuration is applied to a second partition. Thus, during the time interval, the first partition processes events of a data stream in accordance with the target configuration, and the second partition processes events of the data stream in accordance with the source configuration.

During decoding of a CU coded in a combined inter and intra prediction (CIIP) mode and with luma mapping with chroma scaling (LMCS) enabled, a plurality of reconstructed samples of a luma component are obtained in a mapped domain. The reconstructed samples of the luma component are converted from the mapped domain into an original domain by applying inverse mapping associated with the LMCS to obtain converted samples of the luma component in the original domain. Chroma scaling factors for decoding chroma samples of the CU are derived by using corresponding reconstructed samples of the luma component without clipping.
