Data auditing is a system that tracks changes to tables' contents over time.
PostgreSQL has a robust set of features which we can leverage to create a generic auditing solution in 150 lines of SQL.
Auditing is particularly useful for historical analysis. To demonstrate, imagine you have a `users` table that tracks when a user is online.
You might add a `status` column which can have one of two values: `online` and `offline`. How would you track how long a user is online for throughout an entire month?
An auditing system would track every change with timestamps, and so you can measure the difference between each timestamp and sum them up for the entire month.
The goals of our auditing solution are:
- low maintenance
- easy to use
- fast to query
To demonstrate what we're working towards, the following example shows what we'll have at the end of the blog post:
```sql
-- create a table
create table public.members(
id int primary key,
name text not null
);
-- Enable auditing on the new table
select audit.enable_tracking('public.members');
```
Produce some records to audit
```sql
-- create a new record
insert into public.members(id, name) values (1, 'foo');
-- edit the record
update public.members set name = 'bar' where id = 1;
-- delete the record
delete from public.members;
```
Review the audit log
```sql
select * from audit.record_history
```
```markdown
id | record_id | old_record_id | op | ts | table_oid | table_schema | table_name | record | old_record
----+--------------------------------------+--------------------------------------+--------+-------------------------------------+-----------+--------------+------------+--------------------------+--------------------------
2 | 1ecd5ff0-1b6b-5bc2-ad80-1cb19769c081 | | INSERT | Mon Feb 28 18:13:52.698511 2022 PST | 16452 | public | members | {"id": 1, "name": "foo"} |
3 | 1ecd5ff0-1b6b-5bc2-ad80-1cb19769c081 | 1ecd5ff0-1b6b-5bc2-ad80-1cb19769c081 | UPDATE | Mon Feb 28 18:13:52.698511 2022 PST | 16452 | public | members | {"id": 1, "name": "bar"} | {"id": 1, "name": "foo"}
4 | | 1ecd5ff0-1b6b-5bc2-ad80-1cb19769c081 | DELETE | Mon Feb 28 18:13:52.698511 2022 PST | 16452 | public | members | | {"id": 1, "name": "bar"}
(3 rows)
```
Notice that our `record_id` and `old_record_id` stayed constant as we updated the row so we can easily query for a single row's history over time!
## Lets get building
### Namespace
To quote a tenet from [the zen of python](https://www.python.org/dev/peps/pep-0020/):
> Namespaces are one honking great idea -- let's do more of those!
>
So first things first, we'll create a separate schema named `audit` to house our auditing entities.
```sql
create schema if not exists audit;
```
### Storage
Next, we need a table to track inserts, updates and deletes.
Classically, an audit table's schema mirrors the table being audited and appends some metadata columns like the commit's timestamp. That solution has a few maintenance challenges:
- enabling auditing on a table requires a database migration
- when the source table's schema changes, the audit table's schema must also change
So instead, we'll lean on PostgreSQL's schema-less [`JSONB` data type](https://www.postgresql.org/docs/current/datatype-json.html) to store each record's data in a single column.
That approach has the added benefit of allowing us to store multiple tables' audit history in a single audit table.
```sql
create table audit.record_version(
id bigserial primary key,
-- auditing metadata
record_id uuid, -- identifies a new record by it's table + primary key
old_record_id uuid, -- ^
op varchar(8) not null, -- INSERT/UPDATE/DELETE/TRUNCATE
ts timestamptz not null default now(),
-- table identifiers
table_oid oid not null, -- pg internal id for a table
table_schema name not null, -- audited table's schema name e.g. 'public'
table_name name not null, -- audited table's table name e.g. 'account'
-- record data
record jsonb, -- contents of the new record
old_record jsonb -- previous record contents (for UPDATE/DELETE)
);
```
<details>
<summary>Postgres version compatibility</summary>
<p>
The table above uses PostgreSQL's built-in <a href="https://www.postgresql.org/docs/14/functions-uuid.html">uuid functionality</a>, which is available from version 14.
For backwards compatibility you can use the uuid-ossp extension.
</p>
<p>
<code>create extension if not exists "uuid-ossp";</code>
</p>
</details>
### Query Patterns
An audit log doesn't do us much good if its too slow to query! There are 2 query patterns we think are table stakes (😉) for an audit system:
**Changes to a Table in a Time Range**
For time slices, we need an index on the `ts` column. Since the table is append-only and the `ts` column is populated by insertion date, our values for `ts` are naturally in ascending order.
PostgreSQL's builtin [BRIN index](https://www.postgresql.org/docs/current/brin-intro.html) can leverage that correlation between value and physical location to produce an index that, at scale, is many hundreds of times smaller than the default (BTREE index) with faster lookup times.
```sql
-- index ts for time range filtering
create index record_version_ts
on audit.record_version
using brin(ts);
```
For table filtering, we've included a `table_oid` column which tracks PostgreSQL's internal `integer` identifier. We can add an index to this column instead of the `table_schema` and `table_name` columns, minimizing the index size and offering better performance.
```sql
-- index table_oid for table filtering
create index record_version_table_oid
on audit.record_version
using btree(table_oid);
```
**Changes to a Record Over Time**
One of the downsides to storing each row's data as `jsonb` is that filtering based on a column's value becomes very inefficient. If we want to look up a row's history quickly, we need to extract and index a unique identifier for each row.
For the globally unique identifier, we'll use the following structure
```
[table_oid, primary_key_value_1, primary_key_value_2, ...]
```
and hash that array as a UUID v5 to get an efficiently indexable UUID type to identify the row that is robust to data changes.
We'll use one utility function to lookup a record's primary key column names:
```sql
create or replace function audit.primary_key_columns(entity_oid oid)
returns text[]
stable
security definer
language sql
as $$
-- Looks up the names of a table's primary key columns
select
coalesce(
array_agg(pa.attname::text order by pa.attnum),
array[]::text[]
) column_names
from
pg_index pi
join pg_attribute pa
on pi.indrelid = pa.attrelid
and pa.attnum = any(pi.indkey)
where
indrelid = $1
and indisprimary
$$;
```
and another to consume the `table_oid` and primary key, converting the result into the record's UUID.
```sql
create or replace function audit.to_record_id(
entity_oid oid,
pkey_cols text[],
rec jsonb
)
returns uuid
stable
language sql
as $$
select
case
when rec is null then null
-- if no primary key exists, use a random uuid
when pkey_cols = array[]::text[] then uuid_generate_v4()
else (
select
uuid_generate_v5(
'fd62bc3d-8d6e-43c2-919c-802ba3762271',
(
jsonb_build_array(to_jsonb($1))
|| jsonb_agg($3 ->> key_)
)::text
)
from
unnest($2) x(key_)
)
end
$$;
```
Finally, we index the `record_id` and `old_record_id` columns that contain these unique identifiers for fast querying.
```sql
-- index record_id for fast searching
create index record_version_record_id
on audit.record_version(record_id)
where record_id is not null;
-- index old_record_id for fast searching
create index record_version_old_record_id
on audit.record_version(record_id)
where old_record_id is not null;
```
### Enrollment
Okay, so we have a home for our audit data that we're confident it can be queried efficiently. Now how do we populate it?
We need the audit table to populate without end-users making any changes to their transactions. So we'll set up a [trigger](https://www.postgresql.org/docs/current/sql-createtrigger.html) to fire when the data changes. In this case, we'll fire the trigger once for every inserted/updated/deleted row.
```sql
create or replace function audit.insert_update_delete_trigger()
returns trigger
security definer
language plpgsql
as $$
declare
pkey_cols text[] = audit.primary_key_columns(TG_RELID);
record_jsonb jsonb = to_jsonb(new);
record_id uuid = audit.to_record_id(TG_RELID, pkey_cols, record_jsonb);
old_record_jsonb jsonb = to_jsonb(old);
old_record_id uuid = audit.to_record_id(TG_RELID, pkey_cols, old_record_jsonb);
begin
insert into audit.record_version(
record_id,
old_record_id,
op,
table_oid,
table_schema,
table_name,
record,
old_record
)
select
record_id,
old_record_id,
TG_OP,
TG_RELID,
TG_TABLE_SCHEMA,
TG_TABLE_NAME,
record_jsonb,
old_record_jsonb;
return coalesce(new, old);
end;
$$;
```
## Public API
Finally, we'll wrap up the trigger creation and removal process behind a clean, idempotent, user facing API.
The API we'll expose for enabling auditing on a table is
```sql
select audit.enable_tracking('<schema>.<table>'::regclass);
```
and for disabling tracking
```sql
select audit.disable_tracking('<schema>.<table>'::regclass);
```
Under the hood, those functions register our auditing trigger against the requested table.
```sql
create or replace function audit.enable_tracking(regclass)
returns void
volatile
security definer
language plpgsql
as $$
declare
statement_row text = format('
create trigger audit_i_u_d
before insert or update or delete
on %I
for each row
execute procedure audit.insert_update_delete_trigger();',
$1
);
pkey_cols text[] = audit.primary_key_columns($1);
begin
if pkey_cols = array[]::text[] then
raise exception 'Table % can not be audited because it has no primary key', $1;
end if;
if not exists(select 1 from pg_trigger where tgrelid = $1 and tgname = 'audit_i_u_d') then
execute statement_row;
end if;
end;
$$;
create or replace function audit.disable_tracking(regclass)
returns void
volatile
security definer
language plpgsql
as $$
declare
statement_row text = format(
'drop trigger if exists audit_i_u_d on %I;',
$1
);
begin
execute statement_row;
end;
$$;
```
And we're done with 2 lines of code to spare!
### Performance
Auditing tables always reduces throughput of inserts, updates, and deletes. In cases where throughput is less than 1000 writes per second the overhead is typically negligible. For tables with a higher write frequency, consider logging changes outside of SQL with a tool like [pgAudit](https://www.pgaudit.org/).
### Do I really expect you to copy/paste all that?
Nope, for a turnkey solution to auditing in PostgreSQL, we've packaged this script into an extension with some extra goodies like `TRUNCATE` support. Check it out at https://github.com/supabase/supa_audit.
