java - Spring Data Cassandra throws Query timed out after PT2S after two inserts in the DB

Question

Two myRepository.save(myObject) requests are passing just fine but starting with the 3rd one it is failing with the following error although I'm saving (updating) the same object

org.springframework.data.cassandra.CassandraUncategorizedException: SessionCallback; CQL [INSERT INTO ...]; Query timed out after PT2S; nested exception is com.datastax.oss.driver.api.core.DriverTimeoutException: Query timed out after PT2S

I tried to increase request timeout but it still fails even after it:

spring.data.cassandra.request.timeout=15s

There is no additional configuration except for custom converter. Making the same inserts via cqlsh works fine.

Does anyone know why it is happening?

Dependencies:

1. org.springframework.data:spring-data-cassandra:3.1.2
2. org.springframework.boot:spring-boot-starter-data-cassandra:2.4.1
3. com.datastax.oss:java-driver-core:4.9.0
