global cassandra database #32

Open haraldschilly opened 10 years ago

haraldschilly commented 10 years ago

Similar to #31: A global instance of cassandra, where users can get read/write access for their dedicated space and other projects have read-only access. The benefit of #31 is flexibility, while this one here might give better performance. Both approaches might also work hand-in-hand, where the files serve as the raw input data and inside cassandra sits the processed information.

since the GCE infrastructure is in use, it's probably a better idea to let users access cloudstore or bigtable directly.

That's not clear at all. So far my experience with all Google infrastructure like that has been that it has bad latency, whereas a local cassandra is much better. Also, it is free to access a local cassandra, but costs per query to cloudstore/bigtable.
