The main question: how can we prove the scalability of KSM with minimal effort? > 1. The goal is to prove that KSM could handle 1-10 billion of keys without any problem. > 2. 10 000 000 000 * 10 kbyte object = 10 Terrabyte space. But we need to test only the KSM part. > 3. With a low level data generator we can generate the volumes/buckets/keys directly to the ksm.db (rocksdb). We can fake the block allocation and use exactly the same containerid/localid for all the keys. With this method we can test the read/list methods without any problems (all of the keys could be downloaded. > 4. With this storage optimization we can test 10 billion keys locally with a specific docker-compose setup where the local db-s are mounted from the local directory > 5. The data could be generated (takes some time) or could be uploaded after a generation > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
