   Author : Felix Nilsson; Daniel Mihajlovic; [2022]
   Keywords : Resource provisioning; Cloud service platform; Optimizing cost; Database; Performance; Metrics; Technology and Engineering;

   Abstract : As cloud service providers becomes more prevalent, so does questions related to cost efficiency of hosted resources. Payment models for cloud hosted resources tend to be either subscription based or pay-as-you-go for computing resources, in this case for compound metrics of CPU, Data IO and Log IO. READ MORE

4. 3. Dynamic First Match : Reducing Resource Consumption of First Match Queries in MySQL NDB Cluster

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Hara Kumar; [2020]
   Keywords : “Query Optimization”; “Distributed Databases”; “First Match Query”; Frågaoptimering; ”distribuerad databas”; “första match frågor”;

   Abstract : Dynamic First Match is a learned heuristic that reduces the resource consumption of first match queries in a multi-threaded, distributed relational database, while having a minimal effect on latency. Traditional first match range scans occur in parallel across all data fragments simultaneously. This could potentially return many redundant results. READ MORE

6. 5. Offline Approximate String Matching forInformation Retrieval : An experiment on technical documentation

   University essay from JTH. Forskningsmiljö Informationsteknik

   Author : Simon Dubois; [2013]
   Keywords : Algorithm comparison; Approximate string matching; Information retrieval; Offline string matching; Overlap coefficient; Phonetic indexation; String distance; String metric; String searching algorithm;

   Abstract : Approximate string matching consists in identifying strings as similar even ifthere is a number of mismatch between them. This technique is one of thesolutions to reduce the exact matching strictness in data comparison. In manycases it is useful to identify stream variation (e.g. READ MORE
