Hi, I use MonetDB production together with Pentaho BI Server and Saiku, works very well and never had problems. I am currently about 30 million entries in a table of about 40 columns, occupying 9G disk. I'll use it now on other projects that this volume will increase a lot. On what basis of size and number of records you have experience and have arrived? Use in production? I was worried because a few days ago I had a corrupt basis, that is, some columns were blank after restarte the bank, do not know if is related to the data base or was disk failure, to join if I do not have evidence of failure disk, but I can not say.
