Flint

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

Flint imports latency table from cloudping with the 90th percentile and a single day timeframe (see config.go). 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

• Tab: switch the focus
• p: toggle the protocol
