Secondary index recreated even if it already exists about cassandra-driver-mapping

No, this is not expected and indexes should not be recreated.
please provide the entity class sample which you did above but along with the properties declaration

[DBatOWL]

@Table(name = "messages_by_conversation", //
    indexes = { @Index(columnList = "msgid"), @Index(columnList = "resource"), @Index(columnList = "senderid") })
@TableProperties(values = { @TableProperty("CLUSTERING ORDER BY (deletedOn ASC, timeSent DESC)") })
public class MessagesByConversation {

    @EmbeddedId
    private ConversationMessageKey key;

    @Column(columnDefinition = "timeuuid")
    private UUID msgId;

    @Column
    private String resource;

    @Column
    private String xmppId;

    @Column
    private String xmppThreadId;

    @Column(columnDefinition = "timeuuid")
    private UUID senderId;

    @Column
    private String content;

    @Column
    private Map<UUID, String> addresses;
}

public class ConversationMessageKey {

    @Column(columnDefinition = "timeuuid")
    private UUID convId;

    @Column
    private long deletedOn = 0;

    @Column
    private long timeSent;
}

For briefness I've removed the getters/setters but they all follow the same pattern as follows

    public ConversationMessageKey getKey() {
        return key;
    }

    public MessagesByConversation setKey(ConversationMessageKey value) {
        key = value;
        return this;
    }

BTW, I have the system.log file from a period where the app started that shows the creation/initialization of the indexes. Problem is I don't know how to attach it to the issue, seems I can only attach images, not text files. If you would like a copy of the log, let me know, along with where I can send it, and I'll get it to you.

I figured the issue:
you don't have name for indexes and that's why my program was recreating it each time. CZ name on entity didn't match with name in cassandra.
I pushed fix to not recreate the index for the column if it's already in cassandra.
Please reload from maven.

p.s.
Giving a name to index would also fix it.
