# KqpRun tool
Tool can be used to execute queries by using kikimr provider.
For profiling memory allocations build kqprun with ya make flag `-D PROFILE_MEMORY_ALLOCATIONS -D CXXFLAGS=-DPROFILE_MEMORY_ALLOCATIONS`.
## Examples
### Queries
* Run select 42:
```(bash)
./kqprun --sql "SELECT 42"
```
* Queries shooting:
```(bash)
./kqprun --sql "SELECT 42" -C async --loop-count 0 --loop-delay 100 --inflight-limit 10
```
### Logs
* Setup log settings (`-C query` for clear logs):
```(bash)
./kqprun --sql "SELECT 42" -C query --log-default=warn --log KQP_YQL=trace --log-file query.log
```
* Trace opt:
```(bash)
./kqprun --sql "SELECT 42" -C query -T script
```
* Runtime statistics:
```(bash)
./kqprun --sql "SELECT 42" --script-statistics stats.log --script-timeline-file timeline.svg
```
### Cluster
* Embedded UI:
```(bash)
./kqprun -M 32000
```
Monitoring endpoint: http://localhost:32000
* gRPC endpoint:
```(bash)
./kqprun -G 32000
```
Connect with ydb CLI: `ydb -e grpc://localhost:32000 -d /Root`
* Static storage:
```(bash)
./kqprun -M 32000 --storage-path ./storage --storage-size 32
```
* Create serverless domain and execute query in this domain:
```(bash)
./kqprun -M 32000 --shared my-shared --serverless my-serverless --sql "SELECT 42" -D /Root/my-serverless
```
