-------------------------------------------
Summary: Cost of deserializing cluster metadata may become
prohibitive with a large number of peers
Key: CASSANDRA-21224
URL: https://issues.apache.org/jira/browse/CASSANDRA-21224
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Marcus Eriksson
Assignee: Marcus Eriksson
When building the Directory component of ClusterMetadata, the entire set of
nodes is traversed to calculate the min, max and common serialization versions.
Deserializing a directory from a set of bytes (e.g. when reading a snapshot
from the system table or off the wire) is inefficient and creates a new
temporary Directory instance each time a node is added. In large clusters this
may have a noticeable effect on loading time.
