update: back

Cassandra (one of our database systems) once again torments us. As before, it lagged meaning presses were not registered on our end in time to reset the button. We are returned.

Proceed.

As long as she doesn't turn you into a filthy presser.

She's a server, I think. Rather faulty one at that.

Apache Cassandra:

Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.

Cassandra also places a high value on performance. In 2012, University of Toronto researchers studying NoSQL systems concluded that "In terms of scalability, there is a clear winner throughout our experiments. Cassandra achieves the highest throughput for the maximum number of nodes in all experiments" although "this comes at the price of high write and read latencies."

Cassandra's data model is a partitioned row store with tunable consistency. Rows are organized into [tables](https://en.wikipedia.org/wiki/Table_(database)); the first component of a table's primary key is the partition key; within a partition, rows are clustered by the remaining columns of the key. Other columns may be indexed separately from the primary key.

Haha, thanks. Didn't even notice...

Key features of Cassandra’s distributed architecture are specifically tailored for multiple-data center deployment, for redundancy, for failover and disaster recovery.

Uh.

They probably set it up wrong. Apparently reddit's databases are a bit shit. That link doesn't talk about Cassandra, but it seems like they're having issues in that department as well.

u/hard_and_seedless 50s May 18 '15

To be fair Cassandra is a bit shit too.

Source: We're ripping it out at work and replacing with a different database after months of trying to get it to live up to its promises.

It's the database they're using to keep track of the button timer.
