Hello, Would you please advise a proper format for dates, we have a huge data and need to optimize the cache to find more as possible data in cache instead of requesting for creating them. the current date format is dd.MM.yyyy which is a single attribute in fqn (i.e. 24.10.2007) /root | | /10.12.2007 --> from Date | | /11.12.2007 --> to Date | | /Data1 | | /Data2 | do you think that using a format like 2007/10/24 or 24/10/2007 and put every date part as a single fqn would improve or worsen the cache? /root | | /10 | /12 | /2007 | | /11 | /12 | /2007 | | /Data1 | | /Data2 | Thank you.
