Inserting and deleting data from the console

Create a sorted dynamic table:

yt create table //path/to/table --attributes \
'{dynamic=%true;schema=[{name=id;type=uint64;sort_order=ascending};{name=first_name;type=string};{name=last_name;type=string}]}'

Mount a table:
```
yt mount-table //path/to/table
```

Write data:

echo '{id=1;first_name=Ivan;last_name=Ivanov}; {id=2;first_name=Petr;last_name=Petrov};{id=3;first_name=Sid;last_name=Sidorov}' |
yt insert-rows //path/to/table --format yson

Read data:

yt select-rows '* from [//path/to/table]' --format json
{"id":1,"first_name":"Ivan","last_name":"Ivanov"}
{"id":2,"first_name":"Petr","last_name":"Petrov"}
{"id":3,"first_name":"Sid","last_name":"Sidorov"}

echo '{id=1};{id=3}' | yt delete-rows //home/dev/test_dyn_table --format yson

Read data:

yt select-rows '* from [//path/to/table]' --format json
{"id":2,"first_name":"Petr","last_name":"Petrov"}
