Hi,
I'm a newbie to HEAP storage engine internals. I came across the comment as shown below in
include/heap.h. It would really be of great help if any one could elaborate on it.
/*
Heap table records and hash index entries are stored in HP_BLOCKs.
HP_BLOCK is used as a 'growable array' of fixed-size records. Size of record
is recbuffer bytes.
The internal representation is as follows:
HP_BLOCK is a hierarchical structure of 'blocks'.
A block at level 0 is an array records_in_block records.
A block at higher level is an HP_PTRS structure with pointers to blocks at
lower levels.
At the highest level there is one top block. It is stored in HP_BLOCK::root.
See hp_find_block for a description of how record pointer is obtained from
its index.
See hp_get_new_block

Thanks in advance,
Vishwa
