Initially, we partition the file into small enough sections called "runs" that can be accommodated in main memory. It is essential to have the MergeSort algorithm/code to sort each individual run. External Sorting External sorting refers to a group of sorting algorithms that are capable of hand...
–Modified init.ora parameters in your source database that you would not be permitted to alter in ADB. e.g. db_block_checksum, enable_ddl_logging, encrypt_new_tablespaces, local_listener, tablespace_encryption_default_algorithm, tde_configuration, use_large_pages By default, the output gets t...
FMsort is the first algorithm that uses the characteristics of SSDs to optimize the merging phase of external sorting. Shen proposes SMR-EMS (Shingled Magnetic Recording based External Merge Sort) strategy for SMR-based large-scale storage systems to alleviate the negative impacts of sequential wri...
In this work, we propose ActiveSort, a novel mechanism to improve the external sorting algorithm using the concept of active SSDs. External sorting is used extensively in the data-intensive computing frameworks such asHadoop. By performing merge operations on-the-fly within the SSD, ActiveSort ...
