Activate clang-tidy warning "readability-container-contains"
This check suggests replacing <Container>.count() by
<Container>.contains() which is more speaking and in case of
multimaps/multisets also faster.

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.

Update MergeTreeDataPartChecksum.cpp 2021-04-02 15:57:30 +03:00

9f25ee3719 Replaced removing checksums.txt with version
with the explicit data loading and verification.

If the function fails, the exception will re-throw upper,
cancelling the fetch in the handling of the replicated log entry,
but this event will also wake the PartCheckThread, which will
issue a re-fetch.

2ccdb7ef5c Multiple small code and test updates
- Updated the docs to make everything clear.
- Multiple small logger fixes.
- Changed the attach_part command -- now it's after check for the
covering parts -- motivation is to do less work with the checksums
fetching.
- Better logging in the integration test.
