Performance analysis of MARS logging, checkpointing, and recovery

Abstract

The results of a performance analysis used to compare MARS (a main-memory recoverable database with stable log) and MM-DBMS (different main-memory database management system) are reported. With equal numbers and sizes of log records, MARS supports a higher transaction throughput rate than does MM-DBMS. Even with larger numbers of log records, a rate of 1500 transactions per second can be supported by MARS logging. The MARS checkpointing rates are comparable to those of MM-DBMS. In all situations, MARS recovery outperforms that of MM-DBMS.<>
