Exponential Retry for Tracking event processor not happening for transient exceptions when using postgres JdbcTokenStore

See original GitHub issue

Whenever any tracking processor enters retry mode it should attempt to retry in 1s, 2s, 4s, 8s, 16s and so on till it reaches max interval of 60s and thereafter retrying in every 60s. But this behaviour is not observed when using JdbcTokenStore with postgres

Basic information

Axon Framework version: 4.5.3
JDK version: 11
Complete executable reproducer if available (e.g. GitHub Repo): https://github.com/shubhojitr/axon-retry.git

Note: please use below property to toggle between JPA and JDBC token store in the sample repository provided to replicate this issue

token-store:
  jdbc:
    enable: true

Steps to reproduce

Axon configurations:


    @Bean
    public CommandGateway sCSmartPayCommandGateway(org.axonframework.config.Configuration configurer) {
        CommandBus commandBus = configurer.commandBus();
        commandBus.registerHandlerInterceptor(new LoggingInterceptor<>());
        CommandGatewayFactory gatewayFactory = CommandGatewayFactory.builder().commandBus(commandBus).build();
        return gatewayFactory.createGateway(CommandGateway.class);
    }

    @Bean
    @ConditionalOnMissingBean
    public PropagatingErrorHandler propagatingErrorHandler() {
         return PropagatingErrorHandler.instance();
    }

    @Bean
    public TokenStore tokenStore(DataSource dataSource, @Qualifier("serializer") Serializer serializer) {
       return JdbcTokenStore.builder()
                             .connectionProvider(new DataSourceConnectionProvider(dataSource))
                             .serializer(serializer)
                             .claimTimeout(Duration.ofSeconds(10))
                             .schema(tokenSchema())
                             .contentType(byte[].class)
                             .nodeId(ManagementFactory.getRuntimeMXBean().getName())
                             .build();

    }

    private TokenSchema tokenSchema() {
        return TokenSchema.builder().setTokenTable("token_entry_jdbc")
                          .setProcessorNameColumn("processor_name").setSegmentColumn("segment")
                          .setTokenColumn("token").setTokenTypeColumn("token_type")
                          .setTimestampColumn("timestamp").setOwnerColumn("owner").build();
    }

Token entry sql :

CREATE TABLE token_entry_jdbc (
	processor_name varchar(255) NOT NULL,
	segment int4 NOT NULL,
	"owner" varchar(255) NULL,
	"timestamp" varchar(255) NOT NULL,
	"token" bytea NULL,
	token_type varchar(255) NULL,
	CONSTRAINT token_entry_pkey_jdbc PRIMARY KEY (processor_name, segment)
);

Expected behaviour

Expected behaviour for a tracking processor once it enters error mode, is to continue retrying until the transient exception cause is rectified. Below logs are from JPATokenStore with postgres where the retry is working correctly.

Actual behaviour

Once the Tracking event processor enters retry mode, its gets stuck after printing Releasing claim on token and preparing for retry in 1s

I just had a call with the customer. For future people experiencing the issue: Injecting the DataSource as a Bean into the JdbcTokenStore creates the issue. Use the DataSource provided by the DataSourceProvider of Axon for it, then it will use the same transaction manager.

Hi @shubhojitr , I’ve tried looking into this with the source code you have provided. The source code did not work out of the box for me due to the resources folder being in the wrong place. But once I got it working, I did get an exponential retry both on the JPA implementation and on the JDBC implementation.

This is of the JDBC implementation:

I did create the token table in a little bit of a different way than you did, perhaps that makes the difference? I used the PostgresTokenTableFactory to create it, as can be seen below in the bean definition:

 @Bean
    @ConditionalOnProperty(name = "token-store.jdbc.enable", havingValue = "true")
    public TokenStore tokenStore(DataSource dataSource, @Qualifier("serializer") Serializer serializer)
            throws SQLException {
        ConnectionProvider connectionProvider = new DataSourceConnectionProvider(dataSource);
        log.info("+++++++++++++++++Configuring JDBCTokenStore++++++++++++++++++++++");
        Class<?> contentTypeClass = byte[].class;
