Subject Re: ROP - Define order of inserts on large commit to multiple tables with relationships?
Date Tue, 19 Apr 2016 16:56:57 GMT
Hi Michael,

Although my setup is not exactly the same, there are definite similarities, namely in the
method to fetch a current revision. I may end up reverting the changes to add the circular
FK relationships... it's probably not much different performance-wise to the server if I have
to fetch a revision by its PK than if I fetch it from the parent PK (a FK on the revision)
and a null replaced_ts, which I've added as indexes on all the revision tables (parent_pk
+ replaced_ts ). Either way the server has to run a query on indexed columns, right?

Hi Adam,

To follow-up on Andrus' comment, have you considered recursive
relationships?  To do so, your TestScript would have getParent() and
getPrevious() type methods/relationships which return a TestScript (if it
exists) plus a parentFK attribute.

I've used the following pattern in the past:

TestScript previousTS = // your current TestScript
TestScript newTS = context.newObject(TestScript.class);
// Copy/set values from previousTS to newTS
...
previousTS.setParent(newTS);
...
context.commitChanges();


This gives you a chain like:

TS <<-> TS <<-> TS <<-> TS <<-> TS

The TS on the left is the oldest revision.  To fetch the active TS, fetch
the one that doesn't have a parent relationship.

mrg
