A dynamic array involves files that are three files of the InnoDB storage Engine: Dyn0dyn.h, Dyn0dyn.ic, and DYN0DYN.C.
This is a basic component feature that is used as a dynamic virtual linear array. The base element of the array is byte. Dynamic array dyn is mainly used for storing MTR lock information and log. Dyn on implementation, if the block needs to split the node, a memory heap is used. The length of the data field that stores the data for each Bl
