These kind of default settings make sense, though. If you really care about lineair writes, you know how to configure it. Same goes for example for PostgreSQL

These kind of default settings make sense, though. If you really care about lineair writes, you know how to configure it. Same goes for example for PostgreSQL [1], that uses Read Committed rather than Serializable transaction isolation by default because for the majority of the people, this is fine, and the performance tradeoffs are worth it.
