Hacking transferring data
between Front-end to backend
Why ?
- Is it good enough to save data in plain-text?
- Does it make sense to compress data?
- Does Http have any feature about compression?
Facts
- Displaying the meters for a medium-size customer is extremely slow ~10 seconds
json
Saving data in text plain is not good enough
vs
gzip
1.8 Mega Bytes
20 Mega Bytes
90% smaller
Upload gzip
with some magic
1. Get content
6 . Return Data
WebEndpoint
2. Download Data
5. Azure Send Data
Authenticated User
enter
WebApp
Normal approach
File size 20Mb
20Mb
20Mb
Azure
File gets transferred twice
1. Get content
6 . Redirect to temporal Url link
WebEndpoint
2. Request Url link File
5. return temporal Url link
Let's Hack it
7. download directly data
Authenticated User
enter
WebApp
1.7Mb
Gzip File size
1.7Mb
Azure
From 10 seconds
to
