LOAD INDEX
Syntax
LOAD INDEX INTO CACHE tbl_index_list [, tbl_index_list] ... tbl_index_list: tbl_name [[INDEX|KEY] (index_name[, index_name] ...)] [IGNORE LEAVES]
Description
The LOAD INDEX INTO CACHE
statement preloads a table index into the key
cache to which it has been assigned by an explicit CACHE INDEX
statement, or into the default key cache otherwise.
LOAD INDEX INTO CACHE
is used only for MyISAM or Aria tables.
The IGNORE LEAVES
modifier causes only blocks for the nonleaf nodes of
the index to be preloaded.
