Hello, I try to estimate the needed RAM for my application. I have created 3 nodes by starting only the Apache.Ignite.exe.
All is done with C# and Apache.Ignite 2.2 Then I created a data loader application which loads up the whole data of my logfiles. The size of all my logfiles are 7.5 GB. When I loaded it up to the Ignite cluster all together need more than 32GB of RAM. My cache is configured as partioned with 0 backups. So I hat thinked that the cluster will need not much more than 16 GB of RAM. Because the file are normal ASCII files which converted to UTF-8 it will twice the amount of data needed to store. The class file I have created has for each field of the logentry one field. Each field I have marked with the attribute [QuerySqlField] and some fields are indexed. The key is of type Guid. Can someone explain why the amount is 4x greater than the raw data ? Thanks & regards Mario
