There Could Be Another Universe Beside Ours

Earth’s oceans are only 5% explored, outer space is supremely larger - and we haven’t explored even a hundredth of a percent of it.

A major factor in database performance is the storage engine used by the database, and more specifically, its tables. Different storage engines provide better performance in one situation over another.


For general use, there are two contenders to be considered. These are MyISAM, which is the default MySQL storage engine, or InnoDB, which is an alternative engine built-in to MySQL intended for high-performance databases. Before we can understand the difference between the two storage engines, we need to understand the term “locking.”


An application or website that has a frequently used table works exceptionally well using the InnoDB storage engine by resolving table-locking bottlenecks. However, the question of using one over the other is a subjective as neither of them is perfect in all situations. There are strengths and limitations to both storage engines. Intimate knowledge of the database structure and query practices is critical for selecting the best storage engine for your tables.


MyISAM will out-perform InnoDB on large tables that require vastly more read activity versus write activity. (now used on aatventure.news because index is possible on varchar(500))


MyISAM’s readabilities outshine InnoDB because locking the entire table is quicker than figuring out which rows are locked in the table. The more information in the table, the more time it takes InnoDB to figure out which ones are not accessible.


If your application relies on huge tables that do not change data frequently, then MyISAM will out-perform InnoDB. Conversely, InnoDB outperforms MyISAM when data within the table changes frequently.


Table changes write data more than reading data per second. In these situations, InnoDB can keep up with large amounts of requests easier than locking the entire table for each one.



But space exploration in real life is just as fascinating as it looks in the movies. Space facts are always interesting to learn! And what we have already learned is mind-blowing.


Did you know, for example, that the farthest we can see into space today is 13.2 billion light years? Or that there’s trillions upon trillions of light years of space beyond the edge of the observable Universe? Or that Black holes aren’t completely black - they have a barely visible hue of their own?


Here are really cool facts about space and they will rock your world!
