# Play with companies and drafts

# Load testing
## 50000 branches
```
docker-compose up -d
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#fifty_thousand_branches" test
```
## Create 7000 companies, then add a commit to every company three times
### Run web app in the first terminal window
```
./mvnw spring-boot:run
```
### Then create 7000 companies th another terminal
```
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#seven_thousand_companies" test
```
### Then create branch for every company three times (sequentially)
```
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#create_draft_for_each_company" test
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#create_draft_for_each_company" test
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#create_draft_for_each_company" test
```
### Then run every-second requests in three terminal windows in parallel
```
watch -n 1 curl -Ss --url 'http://localhost:8080/company'
```
```
watch -n 1 curl -Ss --url 'http://localhost:8080/company'
```
```
watch -n 1 curl -Ss --url 'http://localhost:8080/company'
```
Those requests turned into SQL like
```sql
CALL DOLT_CHECKOUT ('main');
SELECT `company`.`name` AS `name`, `company`.`modified_at` AS `modified_at`, `company`.`id` AS `id`, `company`.`bank_account` AS `bank_account`, `company`.`estimated_size` AS `estimated_size` FROM `company` ORDER BY `company`.`name` ASC LIMIT 0, 20
```
(You can uncomment JDBC logging in `application.yaml`)
Now we can see 20% CPU of dolt in `top`.
I tried to create indexes
```sql
ALTER TABLE company
ADD INDEX company_name USING HASH (name);
ALTER TABLE company
ADD INDEX company_name USING BTREE (name);
```
but it doesn't change the CPU load.
### If we start creating branches again CPU of dolt will be 120%
```
./mvnw -DenableLoadTests=true -Dtest="name.nkonev.examples.companies.VolumeTest#create_draft_for_each_company" test
```
