Update environment variable configurations for all existing FlowX.AI services to support version 5.0 compatibility.

​
Audit core

Elasticsearch configuration migrates from SPRING_ELASTICSEARCH_* to FLOWX_ELASTICSEARCH_* namespace with enhanced index management.

​
Kafka Configuration

Consumer group naming standardized to kebab-case across all FlowX.AI services with new messaging features for enhanced functionality.
Do not modify default consumer group names. We strongly recommend against changing the default consumer group names as this operation can lead to misconfigurations. The application is designed to work and scale with the consumer groups as they are defined by default.

New Kafka features

Resource Update Propagation

Consumer Group: app-resource-update-propagation-group
Threads: 3
Topic: ai.flowx.{env}.application-version.resource.update.propagation.v1

Build Runtime Data

Consumer Group: build-runtime-data-group
Threads: 2
Topic: ai.flowx.{env}.build.runtime-data.v1

Business Rule Sync

Topic: ai.flowx.{env}.application-version.sync.business-rule.in.v1
Purpose: Business rule synchronization

Process Sync (Restructured)

Topic: ai.flowx.{env}.application-version.sync.process.in.v1
Purpose: Enhanced process synchronization

​
Kafka environment variables (optional overrides)

# Resource Update Propagation
KAFKA_TOPIC_APPLICATION_RESOURCE_RESOURCEUPDATEPROPAGATION=ai.flowx.dev.application-version.resource.update.propagation.v1

# Build Runtime Data  
KAFKA_TOPIC_BUILD_RUNTIMEDATA=ai.flowx.dev.build.runtime-data.v1

# Business Rule Sync
KAFKA_TOPIC_APPLICATION_RESOURCE_SYNC_OUT_BUSINESSRULE=ai.flowx.dev.application-version.sync.business-rule.in.v1

# Process Sync (restructured)
KAFKA_TOPIC_APPLICATION_RESOURCE_SYNC_OUT_PROCESS=ai.flowx.dev.application-version.sync.process.in.v1
Automatic Configuration: Most deployments can rely on the built-in naming patterns without explicit environment variable overrides.

​
Integration Designer

​
Storage configuration

Added support for S3 storage for files in Integration Designer.

​
Redis

Added caching when running a workflow.
VariableDefault ValueDescription

SPRING_DATA_REDIS_HOSTspring.redis.host🆕 Redis host

​
Java runtime configuration

FlowX.AI containers and services must rely exclusively on Java-standard environment variables for runtime tuning.
Deprecated variablesStandard ReplacementNotes
JAVA_OPTS, JAVA_TOOL_OPTIONSJDK_JAVA_OPTIONSEnsures compatibility with Java 21 and simplifies container config
Environment-specific memory configurations must now be defined using JDK_JAVA_OPTIONS. Avoid relying on JAVA_OPTS, JAVA_TOOL_OPTIONS or legacy Docker-level overrides — these are no longer processed explicitly.

​
Config profiles

Config profiles are deprecated since 4.7.6 version.
Remove legacy CONFIG_PROFILE usage. Delete any CONFIG_PROFILE environment variable definitions from deployments. This variable is no longer referenced by FlowX.AI services.
