Pavel Tupitsyn commented on IGNITE-22287:
-----------------------------------------
Turns out we need the scale to preserve original `BigDecimal` representation in
Java. If we remove it, tests fail with errors like:
```
Unexpected string representation of value ==> expected: <10> but was: <1E+1>
in
org.apache.ignite.internal.runner.app.client.ItThinClientComputeTest.testAllSupportedArgTypes)
```
and
```
org.opentest4j.AssertionFailedError: expected: <112000> but was: <1.12E+5>
in
org.apache.ignite.internal.runner.app.client.ItThinClientComputeTest.testBigDecimalPropagation([3]
1.12E5, 0)
```
