+# Adding Database Indexes
+
+Indexes can be used to speed up database queries, but when should you add a new
+index? Traditionally the answer to this question has been to add an index for
+every column used for filtering or joining data. For example, consider the
+following query:
+
+```sql
+SELECT *
+FROM projects
+WHERE user_id = 2;
+```
+
+Here we are filtering by the `user_id` column and as such a developer may decide
+to index this column.
+
+While in certain cases indexing columns using the above approach may make sense
+it can actually have a negative impact. Whenever you write data to a table any
+existing indexes need to be updated. The more indexes there are the slower this
+can potentially become. Indexes can also take up quite some disk space depending
+on the amount of data indexed and the index type. For example, PostgreSQL offers
+"GIN" indexes which can be used to index certain data types that can not be
+indexed by regular btree indexes. These indexes however generally take up more
+data and are slower to update compared to btree indexes.
+
+Because of all this one should not blindly add a new index for every column used
+to filter data by. Instead one should ask themselves the following questions:
+
+1. Can I write my query in such a way that it re-uses as many existing indexes
+   as possible?
+2. Is the data going to be large enough that using an index will actually be
+   faster than just iterating over the rows in the table?
+3. Is the overhead of maintaining the index worth the reduction in query
+   timings?
+
+We'll explore every question in detail below.
+
+## Re-using Queries
+
+The first step is to make sure your query re-uses as many existing indexes as
+possible. For example, consider the following query:
+
+```sql
+SELECT *
+FROM todos
+WHERE user_id = 123
+AND state = 'open';
+```
+
+Now imagine we already have an index on the `user_id` column but not on the
+`state` column. One may think this query will perform badly due to `state` being
+unindexed. In reality the query may perform just fine given the index on
+`user_id` can filter out enough rows.
+
+The best way to determine if indexes are re-used is to run your query using
+`EXPLAIN ANALYZE`. Depending on any extra tables that may be joined and
+other columns being used for filtering you may find an extra index is not going
+to make much (if any) difference. On the other hand you may determine that the
+index _may_ make a difference.
+
+In short:
+
+1. Try to write your query in such a way that it re-uses as many existing
+   indexes as possible.
+2. Run the query using `EXPLAIN ANALYZE` and study the output to find the most
+   ideal query.
+
+## Data Size
+
+A database may decide not to use an index despite it existing in case a regular
+sequence scan (= simply iterating over all existing rows) is faster. This is
+especially the case for small tables.
+
+If a table is expected to grow in size and you expect your query has to filter
+out a lot of rows you may want to consider adding an index. If the table size is
+very small (e.g. only a handful of rows) or any existing indexes filter out
+enough rows you may _not_ want to add a new index.
+
+## Maintenance Overhead
+
+Indexes have to be updated on every table write. In case of PostgreSQL _all_
+existing indexes will be updated whenever data is written to a table. As a
+result of this having many indexes on the same table will slow down writes.
+
+Because of this one should ask themselves: is the reduction in query performance
+worth the overhead of maintaining an extra index?
+
+If adding an index reduces SELECT timings by 5 milliseconds but increases
+INSERT/UPDATE/DELETE timings by 10 milliseconds then the index may not be worth
+it. On the other hand, if SELECT timings are reduced but INSERT/UPDATE/DELETE
+timings are not affected you may want to add the index after all.
+
+## Finding Unused Indexes
+
+To see which indexes are unused you can run the following query:
+
+```sql
+SELECT relname as table_name, indexrelname as index_name, idx_scan, idx_tup_read, idx_tup_fetch, pg_size_pretty(pg_relation_size(indexrelname::regclass))
+FROM pg_stat_all_indexes
+WHERE schemaname = 'public'
+AND idx_scan = 0
+AND idx_tup_read = 0
+AND idx_tup_fetch = 0
+ORDER BY pg_relation_size(indexrelname::regclass) desc;
+```
+
+This query outputs a list containing all indexes that are never used and sorts
+them by indexes sizes in descending order.  This query can be useful to
+determine if any previously indexes are useful after all. More information on
+the meaning of the various columns can be found at
+<https://www.postgresql.org/docs/current/static/monitoring-stats.html>.
+
+Because the output of this query relies on the actual usage of your database it
+may be affected by factors such as (but not limited to):
+
+* Certain queries never being executed, thus not being able to use certain
+  indexes.
+* Certain tables having little data, resulting in PostgreSQL using sequence
+  scans instead of index scans.
+
+In other words, this data is only reliable for a frequently used database with
+plenty of data and with as many GitLab features enabled (and being used) as
+possible.

 GitLab's layout contains 2 sections: the left sidebar and the content. The left sidebar contains a static navigation menu.
-This menu will be visible regardless of what page you visit. The left sidebar also contains the GitLab logo

+## Training
+
+> *Note:* Training the Akismet filter is only available in 8.11 and above.
+
+As a way to better recognize between spam and ham, you can train the Akismet
+filter whenever there is a false positive or false negative.
+
+When an entry is recognized as spam, it is rejected and added to the Spam Logs. 
+From here you can review if they are really spam. If one of them is not really
+spam, you can use the **Submit as ham** button to tell Akismet that it falsely 
+recognized an entry as spam.
+
+![Screenshot of Spam Logs](img/spam_log.png)
+
+If an entry that is actually spam was not recognized as such, you will be able
+to also submit this to Akismet. The **Submit as spam** button will only appear
+to admin users.

+Training Akismet will help it to recognize spam more accurately in the future.

+# Description templates
+
+Description templates allow you to define context-specific templates for issue and merge request description fields for your project. When in use, users that create a new issue or merge request can select a description template to help them communicate with other contributors effectively.
+
+Every GitLab project can define its own set of description templates as they are added to the root directory of a GitLab project's repository.
+
+Description templates are written in markdown _(`.md`)_ and stored in your projects repository under the `/.gitlab/issue_templates/` and `/.gitlab/merge_request_templates/` directories.
+
+![Description templates](img/description_templates.png)
+
+_Example:_
+`/.gitlab/issue_templates/bug.md` will enable the `bug` dropdown option for new issues. When `bug` is selected, the content from the `bug.md` template file will be copied to the issue description field.
