Ivan, Will his value be used as a default one as well or only is a possible minimum? As for the defaults, I see that Postgres and Cassandra set 16mb as a default segment size: https://www.postgresql.org/docs/9.1/static/wal-configuration.html https://www.enterprisedb.com/docs/en/10.0/EPAS_Guide_v10/EDB_Postgres_Advanced_Server_Guide.1.45.html
