Then let's kill this one. Thanks for commenting.

> Too many instances of BigVersion

>                 Key: CASSANDRA-13063
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13063
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Simon Zhou
>            Assignee: Simon Zhou
>            Priority: Minor
>
> When debugging with Cassandra 3.0.10 I found 70+ BigVersion objects on a new 
> node after . This was from a cluster created by CMM and had very little data. 
> Since we create a new instance of BigVersion for each SSTable, that would 
> create too many objects, eg, when bootstrapping new node in a cluster with 
> many sstables.
> Looks like sstables can actually share the same BigVersion instance as long 
> as they has same version. What we can do is to create a object cache and only 
> create new object if not found.
> {code}
> ConcurrentHashMap<String, BigVersion> versions = new ConcurrentHashMap<>();
> {code}
> May not be a big deal but a minor improvement.  [~tjake] what do you think?
