Pre-sales topology discovery eats senior engineer hours before a contract exists

ProxySQL the project is GPL — the revenue lives in 'Our experts are readily available to build, support as well as improve the performance & reliability of your Cloud-Based or On-Premise MySQL infrastructure.' Every inbound 'can you help us?' lands on a small (0–25 headcount) team whose senior engineers have to manually drag the same discovery out of every prospect: which backend (Aurora? RDS? Galera? Group Replication? Percona XtraDB? NDB? MariaDB?), what's the read/write ratio, what's the failover policy, are they sharding, what's the QPS, what does mysql_query_rules need to do. Jesmar's own LinkedIn lists nine distinct backend topologies he supports — the matrix is enormous and each branch changes the proposal. That discovery is currently a human Zoom call before anyone has signed anything.
