kv
batch_put
Store multiple KV values in one itemwise batch.
db.kv.put_many(entries: 'Any') -> 'BatchResult'wire kv_batch_put
Writes multiple KV entries using the executor batch contract. Valid items share commit facts where the underlying engine applies them together.
Itemwise batches return one positional item result per input item. The outer batch status summarizes whether all, some, or none of the items succeeded.
