> Key: CASSANDRA-3141
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3141
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.8.3
> Reporter: Benoit Perroud
> Priority: Minor
> Attachments: CachedSizeCF.patch
>
>
> Every time newRow is called, serializedSize iterate through all the columns
> to compute the size.
> Once 1'000'000 columns exist in the CF, it becomes painfull to do at every
> iteration the same computation. Caching the size and incrementing when a
> Column is added could be an option.
