Arya,
We ran into the issue of decreasing insert performance for tables of
hundreds of millions of rows and they are indeed due to index updates.
We tested TimescaleDB (a pgsql plugin) with success in all use cases that
we have. It does a "behind the scenes" single-level partitioning that is
If I run the database on a server that has enough ram to load all the
indexes and tables into ram. And then it would update the index on the HDD
every x seconds. Would that work to increase performance dramatically?

I'm looking to write about 1100 rows per second to tables up to 100 million
rows. I'm trying to come up with a design that I can do all the writes to a
database with no indexes. When having indexes the write performance slows
down dramatically after the table gets bigger than 30 million rows.
