RE: How Many Partitions are Good Performing - Mailing list pgsql-general
Thank you Rakesh and Andrew!
We will not be doing time scaling but we have list of value based of which we will be partitioning the table and list is something around 7500 now.
For short term we are thinking of putting around a thousand partitions and when PG11 releases we will go for each value a partition.
Regards,
Virendra

This is the blog post that Rakesh referenced:
https://blog.timescale.com/time-series-data-postgresql-10-vs-timescaledb-816ee808bac5
Please note, this analysis is done in the context of working with time-series data, where 1000s of chunks is not uncommon because of the append-mostly nature of the workload.

You should have read carefully what I wrote. 1000 is not an upper limit. 1000 partition is the number after which performance starts dropping .
There is a blog in www.timescale.com which also highlights the same.

Can somebody tell us how many partitions are good number without impacting the performance. We are hearing around a thousand, is that a limit. Do we have plan to increase the number of partitions for a table. We would appreciate if somebody can help us with this?
