I noticed in BigTable impl of Cassandra where they store the "Memtable" info periodically onto disk to avoid cold start-ups...
Is it possible to do something like that for Blur's block-cache, preferably in HDFS itself so that both cold start-ups and shard take-overs don't affect end-user latencies... In Cassandra's case, the size of Memtable will typically be 2GB-4GB. But in case of Blur, it could even be100 GB. So I don't know if attempting such stuff is good idea. Any help is appreciated much... -- Ravi
