Make auto bootstrap smarter --------------------------- Key: CASSANDRA-3517 URL: https://issues.apache.org/jira/browse/CASSANDRA-3517 Project: Cassandra Issue Type: Bug Reporter: Chris Goffinet Priority: Minor
Just wanted to create this before I forget. One of the things we noticed when we were looking over the auto bootstrap code: When the bootstrapping node tries to determine its token, it looks at the ring for the node with the most 'load'. It then sends a message to that node to split its range. The function on that node will sample the keys to figure out where it should split the range. This can actually be very bad. If you have a data model where you have very few keys, and very wide rows the token it picks could be very bad. We should make this more auto bootstrap more intelligent than just looking at the node with the most disk space. -- This message is automatically generated by JIRA.
