of some column in your data, such as the user ID. Vitess allows you to choose from a variety of functions (vindexes) to perform this mapping. This allows you to choose the right one to achieve optimal distribution events from the binary log of the underlying MySQL instance. This allows for efficient execution of functions such as VReplication where a subscriber can indirectly receive events from the binary logs of one 462926 19486 mysqld.go:734] mysqld --initialize -insecure failed: /usr/sbin/mysqld: exit status 1, output: mysqld: [ERROR] Failed to open required defaults file: /home/morgo/vitess/vtdataroot/vt_0000000102/my

the tree. Each operator takes as input zero or more rows, and produces as output zero or more rows. This means that the output from one operator becomes the input for the next operator. Operators that that join two branches in the tree combine input from two incoming streams and produce a single output. Evaluation of the execution plan begins at the leaf nodes of the tree. Leaf nodes pull in data from of some column in your data, such as the user ID. Vitess allows you to choose from a variety of functions (vindexes) to perform this mapping.
