AWS documentation also says horizontal physical partitioning of large table data is best practices instead keeping all in one physical file. There are advantages and disadvantages to using InnoDB file-per-table tablespaces, depending on your application. To determine the best approach for your application, go to InnoDB File-Per-Table Mode in the MySQL documentation. We don't recommend allowing tables to grow to the maximum file size. In general, a better practice is to partition data into smaller tables, which can improve performance and recovery times. One option that you can use for breaking a large table up into smaller tables is partitioning. Partitioning distributes portions of your large table into separate files based on rules that you specify. For example, if you store transactions by date, you can create partitioning rules that distribute older transactions into separate files using partitioning. Then periodically, you can archive the historical transaction data th

When You have assigned a task to optimize a database or performance tuning of an application. Then there could be various dimensions to perform this task because slow performance of application could be many more which can not describe on single page but it can be summary in a table like below I found this table that shows database performance and slow running application performance dimension and there activity start procedures. Performance Dimensions Percentage Values Process Strength Activity Strength Remarks Application Design and Business process 25.00% Long Process Lower priority Module wise activity. Database Schema Design - Logical 15.00% Medium Follow best practices Required short downtime Module wise activity. Database Maintenance 15.00% Quick process Required on OLTP Short downtime weekly or monthly. Indexing 15.00% Quick process Required on OLTP Short downtime weekly or monthly Module wise activity. Server Hardware (CPU/Memory/other) 12.00% Medium process Follow

Hello Friends, Continuing my learning and sharing the concept with social media, I have planned something new this year. I will explore Cloud Database and Analytics platform and will write on "YoungDBA" platform. So I have decided to write a new chain of blogs "10 Facts About". This will mainly relate to Cloud Database and Analytics Platform. I will consider Azure at the start and later will add Aws too. 10 facts will contain, 10 important basic information related to any service provided by cloud data platform provider. This is my first post on "10 Facts About". Every week I will choose a service and will share 10 facts about that like I will start with stream analytics, "10 facts about Azure Stream Analytics".  

Hello friends,  If you are talking about data, database , data-warehouse or big data nothing will complete without schema. Schema plays an important role in Data Platform.  Today I am exploring about Schema on write and schema on read in respect of datawarehouse and data lake.  Let see differences. Schema on write  Structured Data,  RDBMS,  OLAP / Data-warehouse.  Heavy ETL (extract-transform-load) role in data movement.  Change in data-model is costly.  work well in range of Data Mart. User have set of questions. Business Analysis. Collect  Data - Apply Schema - Write Data - Analyze. Schema on read  Structure & Un-structured Data.  RDBMS, NoSQ &  Hadoop.  BigData / Data Lake. ELT (extract-load-transform) & Low cost extraction. Schema is just a structured file can be switched dynamically. Ideal for large volume of data. User is exploring data without pre-defined query. Data science & Research. Collect Data - Write Data - Apply Schema- An
