> {{ColumnIndex}} is supposed to be reusing its shallow entry buffer. Instead
> it always allocates as {{buffer}} isn't returned [from
> {{useBuffer}}|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/ColumnIndex.java#L227].
> Additionally, relying on caller to set {{buffer}} after the call is
> error-prone.
