Subject Cassandra 1.0 - is disk seek required to access SSTable metadata
Date Wed, 08 Aug 2012 08:11:18 GMT
Hi all,

older Cassandra versions had to read columns from each SSTable with
positive bloom filter in order to find recent value.
This was optimized with: Improve read performance in update-intensive
workload <https://issues.apache.org/jira/browse/CASSANDRA-2498>
Now each SSTable has metadata - SSTableMetadata.

Bloom filter is stored in RAM, but what about metadata?
Is disk seek required to access it?

Thanks,
Maciej
