2c40dd6a4c Switch Block::NameMap to google::dense_hash_map over HashMap 
Since HashMap creates 2^8 elements by default, while dense_hash_map
should be good here.

aee034a597 Use explicit template instantiation for SystemLog 
- Move some code into module part to avoid dependency from IStorage in SystemLog
- Remove extra headers from SystemLog.h
- Rewrite some code that was relying on headers that was included by SystemLog.h

v2: rebase
v3: squash move into module part with explicit template instantiation
    (to make each commit self compilable after rebase)

Projections 
TODO (suggested by Nikolai)

1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies

3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)

Also need to figure out how prewhere works for projections, and
row_filter_policies.

Merge pull request #11118 from ClickHouse/aku/trace-log-overflow-followup 
A follow-up for trace log overflow in perftests
 2020-05-22 14:29:11 +03:00

087d8ab020 A follow-up for trace log overflow in perftests 
The start was in https://github.com/ClickHouse/ClickHouse/pull/11026
It turned out that the problem was due to the incorrect mutate()
implementation that lead to quadratic amount of column copying. This
problem has since been fixed.

Remove the excessively verbose logging, and also change appendToBlock of
LogElement's to accept mutable columns instead of accepting a block and
mutating it on each call. It looks wasteful, even though it is almost a
noop.

d93b9a57f6 Forward declaration for Context as much as possible. 
Now after changing Context.h 488 modules will be recompiled instead of 582.

365b5207b7 Add log_queries_min_type to filter which entries will be written to query_log 
Can be used to write into query_log only failed queries (i.e. on memory
exceeded error), by using:

  set log_queries_min_type='EXCEPTION_WHILE_PROCESSING'
