Currently going through leaving DD at work. Many potential options, many companies trying to break in. The one that calls to me spiritually is: throw it all in Clickhouse (hosted Clickhouse is shockingly cheap) with a hosted HyperDX (logs and metrics UI) instance in front of it. HyperDX has its issues, but it's shocking how cheap it is to toss a couple hundred TB of logs/metrics into Clickhouse per month (compared to the kings ransom DD charges). And you can just query the raw rows, which really comes in handy for understanding some in-the-weeds metrics questions.
