The importance of databases indexes

Creating the right indexes for your database, is the foundation for optimal database and SQL query performance. If you're currently investing all of your efforts in query optimization, you should know that there are more aspects to think about.

EverSQL Query Optimizer's algorithm takes many factors into consideration to calculate the best indexes for your query. Among those factors are the query structure, table sizes, existing indexes and their cardinality, column types and sizes, the connections between the tables and columns in the query and many other factors.

Therefore, when optimizing with EverSQL, we don't only ask for the query to optimize, but also require the schema structure, to provide you with the best query optimization and indexing recommendations.

Export schema structure using MySQLDump

We strongly recommend that you'll provide EverSQL Query Optimizer with a schema structure exported using mysqldump, to an XML format. The reason for this recommendation is because mysqldump's XML structure dump is the only format that includes extra data (such as tables size, indexes cardinality and more) which can be used to provide better indexing and query optimization recommendations.

mysqldump is a database backup command line utility created by Oracle. The utility is provided as part of the MySQL Server package.

For InnoDB engine users, the following command can be used to export the schema structure using mysqldump:

mysqldump --xml --no-data --single-transaction=true -h localhost -u root -pPassword schema_name > path/to/dump/file

If you're using MyISAM, use the following command:

mysqldump --xml --no-data --lock-tables=false -h localhost -u root -pPassword schema_name > path/to/dump/file

Please make sure to change the following parameters to adjust the command to your environment:

  • "localhost" - should be replaced with your MySQL server name.
  • "root" - should be replaced with a MySQL user with permissions to dump the schema structure.
  • "Password" - the MySQL user's password.
  • "schema_name" - The name of your schema.
  • "path/to/dump/file" - The path to export the schema structure to.

Note: performing the steps above will also exports extra meta data to the file (i.e, table sizes and cardinality information). This information is used by the indexing algorithm of EverSQL Query Optimizer to provide the optimal indexing recommendations.

Once you executed the command and exported the schema structure, you're all ready to upload it to EverSQL Query Optimizer.

Export PostgreSQL schema structure using pg_dump

pg_dump is a popular utility for backing up a PostgreSQL database.
The following command can be used to export the schema structure using pg_dump:

pg_dump -s databasename > schema.sql

Please make sure you set the database name in the command above before executing it.

Once you executed the command and exported the schema structure, you're ready to upload it to EverSQL Query Optimizer.

How can I download pg_dump without installing PostgreSQL?
Currently, there is no easy option just to download the standalone pg_dump. We recommend that you will visit the PostgreSQL download page, install PostgreSQL and only use the pg_dump, which you can find under the bin folder.
