Sentry with Clickhouse v21.8

Hi everyone,

I am testing sentry with clickhouse v21.8 in staging env and I didn’t find any issue but I can’t say with confirmation that everything is working fine. I am starting this thread to know if anyone has tested this before.

I came across an earlier discussion Support for Clickhouse 21.x which says otherwise so I am curious.


Tagging @fpacifici and @lynnagara here as they are the ones working on this.

thanks for testing it out :smiley:
We did not test 21.8 so far. So cannot say for sure whether you will run into problems.
We are planning to move to 21.8 during Q4 2021 and Q1 2022.

Hi @fpacifici

One thing i missed mentioning before is this upstream issue Backwards compatibility broken when nesting Nullable inside LowCardinality data type · Issue #26556 · ClickHouse/ClickHouse · GitHub

Since snuba uses such schema in transactions CH table we would need to be careful about this breaking change.

Thank you!
