- 1 Intro
- 2 The data deluge
- 3 So, this is a datacenter
- 4 What is happening?
- 5 Ok, let's average numbers
- 6 Ok, let's compute the average
- 7 This doesn't make sense
- 8 Let's move it to the storage!
- 9 This makes sense!
- 10 Datacenter requirements
- 11 And my requirement
- 12 What are the options?
- 13 eBPF for networking
- 14 What am I looking for?
- 15 Somewhere in the read path...
- 16 This is the prototype
- 17 Why Filter-Reduce?
- 18 First of all, where to hook the bpf extensions
- 19 Second, what about data
- 20 Third, how much can I
- 21 Well at least it computes the average, right?
- 22 So, to summarize
