MySQL Performance Tuning Online Course Curriculum:MySQL ArchitectureView the steps involved in Query Execution How the Cient/Server Protocol affects MySQLUnderstand how the Query Optimizer does its jobHow the Storage Engine Layer makes MySQL uniqueFinding Candidates for Query OptimizationsMaking use of The Performance Schema, which is a gold mine for spotting querying for optimization because it allows us to measure where the time goesFinding the few queries that are responsible for most of the load on the system. Checking to the top 1000 queries it’s usually not worth your time to optimize.How to find the relevant information out of the plethora of performance views and metrics available in MySQLUnderstand why UPDATE and DELETE statements are also reads even though they are primarily write statements. This will have an impact on I/O, and therefore to the response time.Analyzing the QueriesUnderstand why MySQL creates a query plan, before each query requestHow to read query plans, and understand how each of the underlying node types works on MySQLA series of examples, to show how the EXPLAIN output can be used, to identify where MySQL spends time on your query, and whyWhich are the important pieces of information, to look for in order to spot performance issuesThe Clustered Index and Choosing the Primary KeyWhen we work with index-organized tables, as the ones in MySQL, the choice of the primary index, is very important.We'll see how the primary key, can impact the amount of random, or sequential I/O, the size of secondary inde
