Put Object Meta Data
Using the following SDK method, you can add meta details for a particular object stored in a bucket in Stratus. The Object reference used in the below code snippet is the component instance.
The meta details will be passed as JSON key value pairs. For example, {“meta_key” : “meta_value”}
-
You can use alphanumeric, underscores, or whitespace characters, as well as hyphens, to write your metadata. No other special character is allowed other than the once mentioned.
-
You can fetch the metadata of an object using the HEAD request method. In the response, the metadata will be listed in the key ‘x-user-meta’.
-
The maximum size limit of characters allowed for the overall metadata is 2047 characters. The character count used to determine the size limit also includes the colon “:” special character used to define the key value pair.
