I joined a company where there are 10 content databases created for 10 site collections(SP2013 version). All the databases together has less than 80GB content.
Well I don't know why they created these many content databases. I know that the best practice is to split the content DB if it has over 100GB of content. Here one of the content DB has less than 200 MB content. My question is there any overhead of having too many content databases like this. Should I suggest to merge some content databases?
