Some databases have a feature where a column can be “autoincremented.” In this piece, we’ll explain why GridGain and Apache Ignite do not and what you can do to get equivalent functionality.

The naming varies, but the concept is straightforward: the system automatically generates a key for you if there is no unique business key for a table. Typically, this would be a numeric column, and the data would increase the value by one every time you insert a new record. MySQL and MariaDB have specific SQL syntax for “AUTO_INCREMENT.” SQL Server has a special data type called IDENTITY. Oracle used to make you use a sequence and a trigger, but it has made it a bit easier in recent years.
