Hi @florence-crl, looks great and love the example joining with statement_statistics so that users can view the query text.

Can we add a description on the time window of the workload over which we look for index recommendations? The default behavior including allowing users to flexibly specifying a timestamp.

@kyle-a-wong, can you confirm the default behavior? If i recall, we take all the statements in statement_statistics. And if a timestamp is specified we filter and only consider those the statements after the timestamp.

@kevin-v-ngo yes, the default behavior will return index_recommendations sourced from all statements in statement_statistics. Providing a time stamp, such as select workload_index_rec('2025-05-5') will only provide workload index recs that come after 2025-05-5 00:00:00
