### Change Logs Currently, `hoodie.populate.meta.fields` is not supported in Flink. This config should be used for append mode, so this MR adds support for this case. **Before**, master, 3cb874fd53390b4465a8a8b9acd615b1b7f362cf:  **After**:  | | Before | After | | -- | -- | -- | | CPU samples | 79.8K | 67.9K | | Total time of 60M rows writing | 108 s | 93 s | TPC-H lineitem table is used for profiling. 14% faster write in append mode for Flink when `hoodie.populate.meta.fields = false`. The next possible optimization for this scenario is to think about do we really need Bloom filters in this use case, because it costs 16% of CPU after optimization of this MR:  ### Impact No ### Risk level (write none, low medium or high below) Low ### Documentation Update No need.
