Research on Performance Optimization of Oltp Systems Based on Innodb
نویسنده
چکیده
The technology of flash memory SSDs (solid state drives) which are increasingly adopted in a wide spectrum of storage systems has the potential of changing the database architecture and principles. With the high random access speed and high IOPS of the SSD, this paper describes a secondary buffer pool & readahead solution based on OLTP for MySQL InnoDB which can reduce I/O requests & latency and improve flash-based database system performance a lot. Based on the buffer pool & read-ahead solution, this paper provide an experience on running online transaction processing workloads (TPCC) which show that the database performance will achieve up to 120%-320% improvements.

Optimizing Space Amplification in RocksDB
RocksDB is an embedded, high-performance, persistent keyvalue storage engine developed at Facebook. Much of our current focus in developing and configuring RocksDB is to give priority to resource efficiency instead of giving priority to the more standard performance metrics, such as response time latency and throughput, as long as the latter remain acceptable. In particular, we optimize space e...

The performance of photovoltaic (PV) systems is highly dependent on environmental conditions. Due to probable changes in environmental conditions, the real-time control of PV systems is essential for exploiting their maximum possible power. This paper proposes a new method to track the maximum power point of PV systems using the moth-flame optimization algorithm. In this method, the PV DC-DC co...
متن کاملPerformance Modeling and Analysis of a Database Server with Write-Heavy Workload
Resource-optimization of the infrastructure for service oriented applications require accurate performance models. In this paper we investigate the performance dynamics of a MySQL/InnoDB database server with write-heavy workload. The main objective of our investigation was to understand the system dynamics due to the buffering of disk operations that occurs in database servers with write-heavy ...
