The official Delta Sharing guidance specifies that in order for recipients to use time travel queries and streaming reads , providers must share Delta tables WITH HISTORY . Sharing history ensures the Delta log is included, which enables efficient access to table snapshots and incremental data streams. Additionally, Change Data Feed (CDF) must be enabled prior to sharing if downstream consumers require streaming CDC queries. Without history, recipients cannot perform time travel or streaming queries. Open sharing supports static Delta tables but lacks streaming support. Therefore, sharing tables WITH HISTORY and enabling CDF is the required configuration for both performance and functionality.
