immediate_controls_config

The immediate_controls_config section provides a set of dynamic parameters for fine-tuning YDB components, including DataShard, Coordinator, SchemeShard, BlobStorage, and others. These settings let you adapt cluster behavior to specific scenarios — for example, by configuring thresholds for automatic shard splitting as data grows or load increases.
