Class Method Details

.data_for(key) ⇒ Object

Fetch the stored gzipped blob for a profile storage key ("-") straight from Redis, without materializing the whole record — the Profiles data endpoint streams it to the browser as-is. nil if the HASH is gone. Owns the data HASH-field name so web callers don't hardcode the schema.

def self.data_for(key)
  Wurk.redis { |conn| conn.call('HGET', key, 'data') }
end

Instance Method Details

#data ⇒ Object

The stored blob is gzipped gecko JSON. data returns the raw (gzipped) bytes — the web layer streams them straight to the browser with a gzip Content-Encoding. Returns nil if the HASH expired between list and read.
