EXECUTE ENGINE question

[jdxia]

Regarding the execution engine, the diagram in the document does not match the logic of the actual code.

The document is written like this

But the code is like this

org.apache.shardingsphere.infra.executor.sql.prepare.AbstractExecutionPrepareEngine#prepare(org.apache.shardingsphere.infra.route.context.RouteContext, java.util.Map<java.lang.String,java.lang.Integer>, java.util.Collection<org.apache.shardingsphere.infra.executor.sql.context.ExecutionUnit>, org.apache.shardingsphere.infra.executor.kernel.model.ExecutionGroupReportContext)

ConnectionMode connectionMode = maxConnectionsSizePerQuery < entry.getValue().size() ? ConnectionMode.CONNECTION_STRICTLY : ConnectionMode.MEMORY_STRICTLY;
