After the delta query is executed and the changed IDs (PK) are collected. It
modified the "query" using the "pk" attribute with a value in delta list and
runs it to create the document.
For example:
<entity pk="id" query="select * from books" deltaQuery="select id from books
where modified > '${dataimport.last_index_time}'">
Suppose changed pk given by deltaQuery is [1,5,7] then the following queries
are executed:
select * from books where id = '1';
select * from books where id = '5';
select * from books where id = '7';

Vary the cron job depending on how frequently and by how many documents the
DB is updated. If an existing import is running, additional calls to start
an import operation are ignored.
