Queries on tables that use CITEXT are 4x slower when using Supavisor vs a direct connection to the db

[jensen]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Originally searched on discord and posted there, the amazing garyaustin suggested I post the issue on the Supavisor GitHub. https://discord.com/channels/839993398554656828/1204584952029782026

I also tested this issue with a local install of Supavisor following the instructions found here: https://supabase.github.io/supavisor/

Describe the bug

Queries to tables that use the CITEXT type are taking longer than queries on tables that do not use this type. Even if the query is select * from table. This bug can be described as weird because it does not seem to occur when connecting to the database directly.

Connection	CITEXT	Duration
Supavisor	Yes	1111ms
Supavisor	No	277ms
Direct	Yes	140ms
Direct	No	139ms

Background:

We setup a Supabase instance in eu-west-2, but are doing the development in us-west. This means that our queries have about 110ms of extra latency which is acceptable. Recently we noticed that queries to the users table are taking about 1200-1500ms while queries to other tables are taking less than 300ms. We recently switched to the Supavisor pooler, and do not recall if the queries were slow when we were using PGbouncer.

In an attempt to isolate the issue to Prisma, I tried Drizzle. The queries with Drizzle are also slow on the users tables. The query performance in the Supabase monitoring shows 0.04ms for this query after resetting and running it.

To Reproduce

1. Setup a new Supabase instance, the farther away the more pronounced the difference in duration.
2. Install CITEXT extension
3. Add a table that has a few columns that use the CITEXT type. In our case we have a users table with email, firstName and lastName that are of type CITEXT.
4. Add a table that has a few columns, but do not use the CITEXT type.
5. Connect with Prisma with postgres://postgres.tenant:[email protected]:6543/postgres?pgbouncer=true
6. Query from the first table with something like select * from users and record the duration.
7. Query from the second table with something like select * from centres and record the duration.

Expected behavior

The queries should take the same duration when using the connection pooler.

Additional context

The logs show that the query for centres is approximately the same duration with or without he connection pooler. The users table query duration matches when CITEXT isn't used as a column type within the table. The duration increases as the table uses more columns that with the CITEXT type.

Interesting. Thank you for the detail here!

Maybe something in the wire protocol causes more round trips for citext tables.

We don't do anything specific for any types.

[jensen]

Thank you for taking a look. I didn't imagine anything was being done specifically with types.

Round trips sounds like a good path to investigate since I noticed adding 1 CITEXT type was faster than adding 3. I imagine adding more would slow it down further. It also seemed like the timing scales relative to the overall single query time.

[jensen]

I had a bit of time to point my development instance of supavisor to an eu-west-2 supabase DB. These are the logs from the same query with three different column type configurations.

Query (no CITEXT columns):

Query: SELECT "public"."users"."id", "public"."users"."isArchived", "public"."users"."email", "public"."users"."firstName", "public"."users"."lastName", "public"."users"."password", "public"."users"."phone", "public"."users"."role", "public"."users"."createdAt", "public"."users"."updatedAt" FROM "public"."users" WHERE 1=1 OFFSET $1

It seems to me that at this point the CITEXT extension is incompatible with transaction mode for production purposes. I will work towards finding an alternative.

I created a configuration with Cloudflare that seems to avoid this issue.

Remix (drizzle w/ HTTP proxy) -> CF Worker (connected using a service binding) -> Hyperdrive (CF Pooler) -> DB (direct connection 5432)

I added 10 CITEXT columns to a table and didn't notice any major difference in the query times compared to a table without this type.
