At small scale any log store works; at scale the invoice decides, not the feature list. The four dominant logging backends make fundamentally different storage bets that fix their cost-per-GB and what queries are even fast. A deep dive on the index-everything camp versus the cheap-storage camp, and the ingest discipline that beats all of them.
