Need help with slow query - postgres 12 on linux RHEL 8
Hello folks!
I am having a complex query slowing over time increasing in duration. If anyone has a few cycles that they could lend a hand or just point me in the right direction with this – I would surely appreciate it! Fairly beefy Linux server with Postgres 12 (latest) – this particular query has been getting slower over time & seemingly slowing everything else down. The server is dedicated entirely to this particular database. Let me know if I can provide any additional information!! Thanks in advance!
Here’s my background – Linux RHEL 8 – PostgreSQL 12.17. –
MemTotal: 263216840 kB
MemFree: 3728224 kB
MemAvailable: 197186864 kB
Buffers: 6704 kB
Cached: 204995024 kB
SwapCached: 19244 kB
free -m
total used free shared buff/cache available
Mem: 257047 51860 3722 10718 201464 192644
Swap: 4095 855 3240
Here are a few of the settings in our postgres server:
max_connections = 300 # (change requires restart)
shared_buffers = 10GB
temp_buffers = 24MB
work_mem = 2GB
maintenance_work_mem = 1GB
most everything else is set to the default.
The query is complex with several joins:
SELECT anon_1.granule_collection_id AS anon_1_granule_collection_id, anon_1.granule_create_date AS anon_1_granule_create_date, anon_1.granule_delete_date AS anon_1_granule_delete_date, ST_AsGeoJSON(anon_1.granule_geography) AS anon_1_granule_geography, ST_AsGeoJSON(anon_1.granule_geometry) AS anon_1_granule_geometry, anon_1.granule_is_active AS anon_1_granule_is_active, anon_1.granule_properties AS anon_1_granule_properties, anon_1.granule_update_date AS anon_1_granule_update_date, anon_1.granule_uuid AS anon_1_granule_uuid, anon_1.granule_visibility_last_update_date AS anon_1_granule_visibility_last_update_date, anon_1.granule_visibility_id AS anon_1_granule_visibility_id, collection_1.id AS collection_1_id, collection_1.entry_id AS collection_1_entry_id, collection_1.short_name AS collection_1_short_name, collection_1.version AS collection_1_version, file_1.id AS file_1_id, file_1.location AS file_1_location, file_1.md5 AS file_1_md5, file_1.name AS file_1_name, file_1.size AS file_1_size, file_1.type AS file_1_type, visibility_1.id AS visibility_1_id, visibility_1.name AS visibility_1_name, visibility_1.value AS visibility_1_value

Hi, we'd need `explain (analyze, buffers) select ...` for your query. Ideally, could you put it on https://explain.depesz.com/, with query and `\d`, and provide us with link? Best regards, depesz

I have added an index to the granule_file table and ran a few explains - here are the results.... thanks for the

Hi,
we'd need `explain (analyze, buffers) select ...` for your query.
Ideally, could you put it on https://explain.depesz.com/ <https://explain.depesz.com/>, with query and
`\d`, and provide us with link?
Best regards,

Any chance you can also provide the query that you used in this case,
and `\d` of all tables:
- collection
- file
- granule
- granule_file
- visibility
Here you have example explain that contains all the information:

You did not created the index I recommended before:
CREATE INDEX ON granule_file(granule_uuid);
Try creating this index and show us the new generated plan with `EXPLAIN (ANALYZE, VERBOSE, BUFFERS)` (you can paste it at depesz tool).
PS: As said in the other thread, a primary key on (granule_uuid, file_id) would make more sense, but you need to get rid of null values on these rows before creating the PK.

With this in place, you could also use trigram index on file.name Details: https://www.postgresql.org/docs/current/pgtrgm.html#PGTRGM-INDEX *BUT* The query that you once showed, didn't have any where condition on file.name. So either this is different query, or you are using some view. Please, pretty please, when putting explains on explain.depesz.com always include query it came from, as it makes understanding much easier.
