Great questions.

BigQuery reduces storage costs as even before their recent pricing change, the cost per GB [0] is on par with and slightly lower than s3 storage costs [0], which we can use as a estimated market price for data storage. BigQuery makes money off the querying costs, which we take steps to optimize and minimize, with table partitions, caching, and ui design, both client side and server side. These all help to reduce querying costs. Table partitioning also helps to cut per-GB storage costs by half by switching to long-term logical storage after 90 days.

Of course, using blog storage might possibly result in comparable cost, however, relying on blob storage would likely increase the querying costs (in terms of GET requests) as well as complexity to query across multiple stored objects/buckets, as opposed to relying on BQ to handle the querying.

In the long term, we would likely continue using BQ for our platform infrastructure, unless GCP changes their pricing in a way that adversely affects us. When it comes to self-hosting, it would of course depend on how much complexity one would like to take on, and out-sourcing the storage and querying management is a better option in most cases.

We would not rule out such features, but we consider them nice-to-have features and are very far down the priority list. At the moment we're mostly focused on improving integration with the Supabase products and platform. It is actually possible to log stack traces, and is supported out-of-the-box for certain integrations such as the Logflare Logger Backend [2].

Postgres without any extensions is not optimized for columnar storage, and would not be an optimal experience for such large scale data storage and querying. It is also not advisable to use the same production datastore for both your application and your observability, it is better to keep them separate to avoid coupling. If one really wants to use the same Postgres server for everything, there are extensions that allow for Postgres to work as a columnar store, such as citus[3] and timescaledb[4], and we have not ruled out supporting these extensions as Logflare backends.
