Re: [orientdb] Re: Cores and clusters and classes - oh my!

So, in distributed and with 2.2, the default is one cluster per node, per class on master nodes. And on a single master and with 2.2, the default is one cluster per cpu core per class. Is that correct??? What is the purpose of spreading out of a class with more clusters per cpu core in a

Re: [orientdb] Re: Cores and clusters and classes - oh my!

Good point. I wonder if the cpu cores = # of clusters setting also counts in a distributed system. It wouldn't seem to make too much sense, because "over-chunking" the data can also cause performance issues when querying. Scott -- --- You received this message because you are subscribed to

Re: [orientdb] Re: Cores and clusters and classes - oh my!

I believe this part of the docs explains clusters and nodes properly. You can have nodes with different clusters of a class. But, you can't have different classes in the same cluster. In other words, clusters are groups of records that belong to a certain class only. So, you can't mix and

What is the schema on the class "test2"? Does it extend ORestricted by chance? Either way, I'd venture to say, you might have found a bug. Here is what the fields are for. http://orientdb.com/docs/2.1/Database-Security.html#record-level-security What version of ODB are you on? Scott --
