Write multiple key-value pairs

kv.namespaces.bulk_update(, ) -> NamespaceBulkUpdateResponse

PUT/accounts/{account_id}/storage/kv/namespaces/{namespace_id}/bulk

Writes up to 10,000 key-value pairs to the specified Workers KV namespace from a JSON array, with optional metadata and expiration settings for each pair. Existing values and expirations are overwritten. If neither expiration nor expiration_ttl is specified, the key-value pair will not expire. If both are set, expiration_ttl takes precedence. The entire request must be 100 megabytes or less. The result reports the number of successful writes and any keys that failed and should be retried.
