I liked that is easy just like sql server, but you can create tables or queries easily with one command in SQL (I am not sure if this feature exist for Postgresql).Also when we use it as an RDBMS our users always find its simple because they already know how mysql works since most of their experience are from MYSQL so learning new thing would be hard which will take time until then user has good impression about hyper table itself hence reducing cost by using more powerful tool than what customer actually need. Hyper Table also supports all popular formats such CSV / JSON/ XML etc. Also there's no limit regarding number columns per each row unlike other commercial products out here today including Microsoft Sql Server where size limitation exists sometimes causing issues during loading large files into tabular format. Data storage structure could have been better especially concerning memory usage due mainly cause lack processing power compared too. Sql Servers used nowadaysBut thats only my opinion nothing else - maybe someone knows...
