feature_flags

The feature_flags section enables or disables specific YDB features using boolean flags. To enable a feature, set the corresponding feature flag to true in the cluster configuration. For example, to enable support for vector indexes and auto-partitioning of topics in the CDC, you need to add the following lines to the configuration:

feature_flags:
  enable_vector_index: true
  enable_topic_autopartitioning_for_cdc: true
