Cassandra. Writes that keep working when a machine does not.
A wide-column store built for enormous write volumes across many nodes. One node is fine for trying it. It has no password in this image, so it is only reachable from containers on its networks. Takes a minute or two to be ready. It has no password of its own, so it stays on your networks.

/the-engine
Cassandra, described once. Nothing to guess.
Writes that keep working when a machine does not.
Credentials
This engine has no login of its own, so it is never opened to the internet: only containers on its networks, or the server itself, reach it.
Backups
A copy of its folders, taken while it runs, on a plan you choose, into your own bucket.
| Variable | What it is |
|---|---|
CASSANDRA_CLUSTER_NAME | The cluster’s name. It cannot change once data is written. |
MAX_HEAP_SIZE | The Java heap. Set it together with HEAP_NEWSIZE, or neither. |
HEAP_NEWSIZE | The young generation of the heap — about 100 MB per CPU. |
CASSANDRA_DCoptional | The data centre this node says it is in. |
