==Key-Value Store==
A new [[Store Module]] provides functions to organize values in a persistent main-memory key-value store. The store allows you to speed up access to frequently accessed data.
; Store data:
<syntaxhighlight lang="xquery">
let $email := map:merge(
for $address in db:get('addressbook')//address
return map:entry($address/name, $address/email)
)
return store:put('emails', $email)
</syntaxhighlight>
; Retrieve data:
<syntaxhighlight lang="xquery">
let $name := 'Richard David James'
return store:get('email')($name)
</syntaxhighlight>
The store is persistent: Contents are written to disk. If BaseX is restarted, all contents will be retrieved from disk again.
