User-defined functions and strategies – SQL parser, sharding, read/write splitting, distributed transactions

In this section, you will learn how to create and configure custom functions. We will start with the SQL parser before looking at data sharding, read/write splitting, and, finally, distributed transactions. The examples and steps you will find in the following sections will empower you to make Apache ShardingSphere truly yours.

Customizing your SQL parser

This section will describe how to use the SQL parser engine, which is compatible with different database dialects. By parsing SQL statements to a message that can be understood by Apache ShardingSphere, enhanced database features can be achieved. Various dialect parsers that are part of the SQL parser are loaded through the SPI method. Therefore, you can handily develop or enrich database dialects.

Implementation

Let's review the necessary code to get started. In this section, you will learn how to...
