1) did you install correct root ca certificates? (curl request work?) 2) which OS do you use (on some OS you need to adjust the path to CA in ssl client configuration of ClickHouse)?

It was never supported / declared to work. So it's definitely a new feature, it seems it may requere some kind of template format in the s3 path instead of simple glob. Do you know how is that problem solved by other DB / frameworks?

There is an issue - you run long INSERT query (for example, insert a terabyte of data in single query) and you will get constantly growing memory usage for query, that is false, because the memory for indices is freed in background merges.

``` -- Configuring done -- Generating done. ... -- Build files have been written to: /data/compile/ClickHouse/build ``` Hm. it looks like the cmake successfully finished. The log of cmake feature tests is unrelated. What happen when you start `ninja` after cmake?

It is a network connectivity issue. The connection has being dropped during the query. ClickHouse will correctly reports it by throwing an exception, at the same time the client may have already read part of the resultset but it will receive the exception as well.

No, they just did not setup testing environment correctly (missing some of configs for server to listen other than localhost).

> 没错，下推后 外层的where条件继续保留 这样在保证结果不变的情况下 提升了查询性能 该特性在哪个版本会发布呢 此优化会引入JOIN的功能性问题(语法优化层无法解决, 需要将谓词优化改写到执行层时才可能解决。目前执行层的改写正在进行中)。

How is it possible if: - data parts are added to the working set (with index) in context of INSERT query; - data parts are removed from the working set in context of background merge?

There is no way to stop the merge quickly. Up to single minutes delay is expected.

I did not use `ninja` at first. I just use `make -j8` to compile it ,and then got the `error message: ...` applied above. After that I install ninja-build and cmake again, then use ninja. Also I got some errors. But it's not very clearly, so I don't record it.

@ibradwan seems you misunderstood something. > I will have to stop the ClickHouse server No, I do NOT see any sense to stop CH. It's unclear how you do snapshots and what is your setup. In some cases `sync` is not enough, because env. can have more caches / raid cache / disk-drive cache.
