 * Write multiple key-value pairs

 * 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.
