Have you ever thought how many values repeating attribute can have? Another interpretations of this question:

- How many records can access list have?
- How many direct subgroups can single group have?
- How many direct members can single group have?
- How many direct/indirect groups can single group belong to?
- …

Let’s check:

/** * @author Andrey B. Panfilov <andrey@panfilov.tel> */ public class Test { public static void main(String[] args) throws Exception { IDfSessionManager sessionManager = new DfClientX() .getLocalClient().newSessionManager(); sessionManager.setIdentity("DCTM_DEV", new DfLoginInfo("dmadmin", "dmadmin")); IDfSession session = sessionManager.getSession("DCTM_DEV"); IDfSysObject object = (IDfSysObject) session.newObject("dm_sysobject"); for (int i = 0; i < 32780; i++) { object.setAuthors(i, String.valueOf(i)); } System.out.println("Saving: " + object.getObjectId()); object.save(); session.flushObject(object.getObjectId()); session = sessionManager.newSession("DCTM_DEV"); object = (IDfSysObject) session.getObject(object.getObjectId()); for (int i = 0; i < 32780; i++) { int value = Integer.parseInt(object.getAuthors(i)); if (value != i) { System.out.println("author[" + i + "] has " + "wrong value of " + value + ", expected: " + i); } } } }

[dmadmin@docu72dev01 ~]$ java Test Saving: 08024be98004be94 author[0] has wrong value of 32768, expected: 0 author[1] has wrong value of 32769, expected: 1 author[2] has wrong value of 32770, expected: 2 author[3] has wrong value of 32771, expected: 3 author[4] has wrong value of 32772, expected: 4 author[5] has wrong value of 32773, expected: 5 author[6] has wrong value of 32774, expected: 6 author[7] has wrong value of 32775, expected: 7 author[8] has wrong value of 32776, expected: 8 author[9] has wrong value of 32777, expected: 9 author[10] has wrong value of 32778, expected: 10 author[11] has wrong value of 32779, expected: 11 author[12] has wrong value of 0, expected: 12 ... author[32767] has wrong value of 32755, expected: 32767 author[32768] has wrong value of 32756, expected: 32768 author[32769] has wrong value of 32757, expected: 32769 author[32770] has wrong value of 32758, expected: 32770 author[32771] has wrong value of 32759, expected: 32771 author[32772] has wrong value of 32760, expected: 32772 author[32773] has wrong value of 32761, expected: 32773 author[32774] has wrong value of 32762, expected: 32774 author[32775] has wrong value of 32763, expected: 32775 author[32776] has wrong value of 32764, expected: 32776 author[32777] has wrong value of 32765, expected: 32777 author[32778] has wrong value of 32766, expected: 32778 author[32779] has wrong value of 32767, expected: 32779

So, the “safe” amount of repeating values is 32767, after that Content Server starts to corrupt data.
