Bitrix innodb vs myisam

Table changes write data more than reading data per second. I expected to see a number less than real size of data MB (m.b. or megabyte). For the MySQL version, the optimization of database interaction is one of the most important points because Bitrix Site Manager uses database operations intensively. MyISAM only has full table-level locking.

A standard format of MySQL is MyISAM. It is also possible to use replication in a way where the storage engine on the slave is not the same as the original storage engine on the master.

Therefore, properties such as ACID-compliance. Remember the screwball. This means that innodb blob uses disk space very inefficiently, and if I want to migrate my project from myisam to innodb , it is need to replace 128gb ssd with tb ssd.

InnoDB in MariaDB and MySQL 5. In my opinion, 6 overhead - bug, but bugs. No doubt, MySql is one of the most used databases worldwide. The great thing about MySql is the flexibility to choose storage engines.

Not sure about the back-up part however.

Does copying the database files in the filesystem directly work for you? There are also other difference such as locking, rollbacks, and full-text searches. These two MySQL engines all come with their pros and cons and will have their benefits and differences which may or may not pose as factors that make their users opt for them. ACID stands for Atomicity, Consistency, Isolation, Durability.

Both innodb and myisam estimate the row count based on statistics they keep on the distribution of keys in an index. MyIsam Vs Innodb Vs Memory – Mysql Storage Engine Comparison. If you’ve decided to use MySQL database for your. Table files may be transferred between computers of various architectures and various operating systems without any conversion. Different storage engines use different methods to calculate row count.

This means that when you are updating a row, only that one row gets locked (which means that another connection to the database cannot modify that row). It is based on the older ISAM code, but it has many useful extensions. Identifying these niches in your database structure can help squeeze the best performance out of your database and associated applications.

To determine whether a table. The space usage with the 4. The upcoming zip-compression will normally save of space. Each storage engine implements a more specific set of features required for a type of workloa and as a result, works differently from other engines.

There is lots more, but those are the basics. FIXED is virtually useless in MyISAM.

Also, foreign keys are not supported. Here’s a couple queries you can use to achieve such.
