      Problem Definition

      Table columnlayoutitem is used for storing Fields schema configs and it doesn't have optimal index structure.
      Snippet from the table:

      select * from columnlayoutitem limit 3;
  id   | columnlayout | fieldidentifier | horizontalposition
-------+--------------+-----------------+--------------------
 10300 |        10000 | issuetype       |                  0
 10301 |        10000 | issuekey        |                  1
 10302 |        10000 | summary         |                  2

      Indexes: 

      \d columnlayoutitem
             Table "public.columnlayoutitem"
       Column       |          Type          | Modifiers
--------------------+------------------------+-----------
 id                 | numeric(18,0)          | not null
 columnlayout       | numeric(18,0)          |
 fieldidentifier    | character varying(255) |
 horizontalposition | numeric(18,0)          |
Indexes:
    "pk_columnlayoutitem" PRIMARY KEY, btree (id)
    "idx_cli_fieldidentifier" btree (fieldidentifier)

      columnlayout is being used during data loading:

      com.atlassian.jira.issue.fields.layout.column.DefaultColumnLayoutManager#transformToColumnLayoutItems
...
 final List<GenericValue> columnLayoutItemGVs = ofBizDelegator.getRelated("ChildColumnLayoutItem", columnLayoutGV, ImmutableList.of("horizontalposition ASC"));

      Suggested Solution

      Add index for columnlayout column 

      CREATE INDEX [IX_columnlayoutitem_COLUMNLAYOUT] ON [jiraDB].[dbo].[columnlayoutitem] ([COLUMNLAYOUT])

      Workaround

      Add index manually
