Abstract
In this work, we captured 36 days of I/O trace from NEXUS 5 and analyzed database usage of each application. We found that 70% of synchronous write I/Os are snet_files_info.db, esO.db, and gmail.com.db. There were 1533 records in snet_files_info.db that has to be updated for Google mobile service which creates write amplification of 6×106. Out of 62 tables in esO.db, only 2 tables were the most frequently used tables, but surprisingly the two tables share almost exact data. mailstore.x@gmail.com.db creates heavy synchronous writes during during checkpoint operation.
