> Hi,
> Now we have `show child paths PATH_PREFIX` to show the children nodes of the
> PREFIX PATH.
> However, sometimes we need more complex queries, like
> 1. show all path prefixes (level6) which start with "root.a.b.*.d"
> (level1=root, level2=a, and level3=b, level4 can be everything, and level5=d).
> 2. show all path prefixes which start with "root.a.b*" (level1= root,
> level2=a and level3 starts with b).
> 3. combine 1 and 2 together. e.g., "root.a.b*.**.d.**", etc..
> 4. For select queries, it is also good to support wildcard like "select *
> from root.a.**.b**" (which means that the level4 starts with 'b');
