Write multiple key-value pairs

client.kv.namespaces.bulkUpdate(, , ?): NamespaceBulkUpdateResponse { successful_key_count, unsuccessful_keys } | null

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

Write multiple keys and values at once. Body should be an array of up to 10,000 key-value pairs to be stored, along with optional expiration information. Existing values and expirations will be overwritten. If neither expiration nor expiration_ttl is specified, the key-value pair will never expire. If both are set, expiration_ttl is used and expiration is ignored. The entire request size must be 100 megabytes or less.
