We enquired about Timescale Cloud, to migrate from Cloud SQL as we could use it to solve a couple of problems in a simpler way and give us a chance to create other solutions when needed. We don't have anything in time series yet but were hoping to have it there to experiment and start dipping our toes but found it a bit expensive.
The pricing seemed more of an all or nothing investment and didn't make sense if we weren't ready to start using the extra functionality just yet. Was hoping that it would be similar to Cloud SQL and just cost extra depending on usage.
