com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table peers_v2

Question

I am developing an application with Spring Boot that connects to cassandra

This is my connection settings

spring.data.cassandra.contact-points=localhost
spring.data.cassandra.keyspace-name=sa_tas_db_cassandra
spring.data.cassandra.schema-action=create_if_not_exists
spring.data.cassandra.username=cassandra

I'm just using a table, which I create by means of a model. Which is the following

import org.springframework.data.cassandra.core.mapping.PrimaryKey
import org.springframework.data.cassandra.core.mapping.Table
import java.time.LocalTime
import java.util.*

@Table
data class CallLog(
    @PrimaryKey
    val callId:UUID,
    val CustomerUsername: String? = null,
    val callDirection: String? = null,
    val callingPartyName:String? = null,
    val callingPartyNumber:String? = null,
    val calledPartyNumber:String? = null,
    val typeOfCall:String? = null,
    val startTime: Date? = null,
    val answerTime: LocalTime? = null,
    val disconnectTime:Date? = null,
    val timeCallForwarded: Date? = null,
    val voicemailSystemAccessNumber:String? = null
)

That's all my cassandra setup

I am also monitoring my application with new relic, and it is generating the following problem

This error does not affect the operation of the application, it only affects the performance

Thanks

Answer 1

This is a part of compatibility test for supporting Cassandra 4.0 that stores information about nodes in the cluster in a table with different name, so driver first assumes that it runs against newer version, and checks this table, and if it receives an error, then it uses the old peers table. It's not possible to reliably detect Cassandra node's features only from version number, that's why it's better to check for table explicitly.

The corresponding code is here .
