Flint

Flint computes expected latencies for the selected set of AWS clients using different replication protocols.

Flint imports latency table from cloudping Instead of going through cloudping, flint can be launched with a provided latency table via -l command-line option. See latency_table_example.txt for an example of latency table configuration file.

Supported protocols

• SwiftPaxos (only with fixed fast quorums)
• Paxos
• N²Paxos (an all-to-all variant of Paxos)
• CURP (over N²Paxos)

Installation

go install github.com/vonaka/flint@latest

Navigation

Flint's text-based UI is powered by tview. It supports mouse events and the following hotkeys:

• Tab: switch the focus
• p: toggle the protocol
• Esc: print current latency table
• e: export latency table for the selected replicas and clients
• i: import latency table from file
• q: quit
