For what it's worth, I have done similar approaches of having an XML file or
files of sort of static configuration like this and I query it at runtime every
time. Performance has always been extremely good, even when there are several
entries. For example, I have one file that has all the language codes for the
2- and 3- char codes that are queried every request. I also have other
situations where rules are saved in the DB as separate XML files and they are
all queried at runtime and the time it takes to do that doesn't even register
in the profiler (0sec). If the queries use the index, then I think this is a
great approach. It's easy to maintain and the code is understandable. Plus it
works across all nodes.

You could store it as XML, then make a map out of it, and use
xdmp:set-server-field() to save the map in memory between requests. Use
xdmp:get-server-field() to retrieve it later. On server restart you'll have to
regenerate the map. You'll also have to generate and save the map once on
every E-node. Note that the map is associated with the entire host, not just
the app server.

Hi All
I have my master
lookup data XML inserted into Marklogic .
<states>
<state>
<code>AL</code>
<desc>Alaska</desc>
</state>
:
:
</states>
I have two ways to
get the description through code
Construct the map with the codes and values and use the
map API to get the description.
Every time traverse the XML to get the description
through code.
Can any one suggest
keeping performance in mind which one is better approach? Is there
any other approach to do this (using any in-built indexing mechanism)?
