SOA Performance Tip : Reduce the MDS size !!!!

Generally, when there is a case where the heap usage is more and you are getting back-to-back full GC in Prod, this is really difficult to handle in production.
When getting into details, MDS is one of the components that is very heavy and already loaded in memory. As a best practice, all XSDs will be stored in MDS which is generally heavy in size, unless they are non-standard xsds. These xsds are having a lot of documentation around it which makes it more than the actual definition. Obviously these documentation help for the reason of better understanding

Tip : See if these documentation can be removed to reduce the size of xsd. This can be done easily with a very powerful tool/utility in Linux. It is the Sed  command. Sed is the ultimate stream editor command that can do wonders.

Lets take an example of such xsd and see how can sed command be used to remove the documentations/enumerations of a xsd file

sed -i '/xsd:documentation/d' sample.xsd
sed -i '/xsd:enumeration/d' sample.xsd

Here you go !!!!… check the size of xsd to see the size getting reduced after removing the documentations/enumerations
Save this modified file and import them back to MDS
