Building on the revolutionary architecture of Gluesync 2.0, this latest release elevates data synchronization with advanced organization capabilities and custom data transformation options. ## What’s new today in 2.1 ### Groups and Chains: a new era in data entity management Gluesync 2.1’s most significant enhancement is the introduction of **Groups and Chains**, transforming how users organize and manage data entities. These features make complex data integration scenarios more intuitive and manageable, providing unprecedented control over your data synchronization processes. ### Groups: logical organization made simple Groups in Gluesync 2.1 serve as a logical organization system for entities, designed to simplify configuration and settings management across multiple related entities. Every new entity is automatically assigned to the “default” group unless specified otherwise.  Gluesync 2.1 Groups interface showing color-coded entity grouping with multiple entities organized by related database functions Key benefits include: - **simplified management**: group related entities together for better organization - **efficient configuration**: apply settings to multiple entities simultaneously - **visual identification**: assign colors to groups for quick visual reference in the UI - **flexible organization**: no impact on execution order or data flow ### Chains: managing entity dependencies Chains take organization a step further by defining physical execution order for entities. This feature is particularly valuable when working with entities that have foreign key relationships, ensuring operations are performed in the correct sequence to maintain data integrity.  Gluesync 2.1 Chains interface showing sequential entity execution order with arrows indicating data flow between dependent tables With Chains, you can: - define explicit execution order for related entities - ensure referential integrity during data synchronization - manage complex data relationships with ease - visualize and control the flow of data between dependent entities Compatible agents currently supporting chains include MS SQL Server (CDC Agent), MS SQL Server (Change Tracking Agent), MySQL Agent, MariaDB Agent, Informix Agent and Db2 for IBM i Agent, with more coming soon. Learn more about it in [Groups and Chains official documentation.](https://docs.molo17.com/gluesync/v2.1/core-hub/groups-and-chains.html) ## Coming soon in 2.1 To address our customers’ real-world needs, we’re releasing key features in phases. ### User Defined Functions (UDFs) _Expected release: early July 2025_ Gluesync 2.1 will introduce **User Defined Functions (UDFs)**, enabling you to write custom code scripts that execute during the data replication process. These scripts will be checked and compiled by the platform, allowing you to implement custom business logic on incoming data. With UDFs, you’ll be able to hook into three main events during data replication: - insert operations: Process new records as they are created - update operations: Transform data when existing records are modified - delete operations: Implement custom logic when records are removed This powerful feature will give you fine-grained control over how data is transformed and processed before reaching the target destination. Gluesync 2.1 will support writing UDFs in **multiple programming languages**: - **Java** - **Kotlin** - **JavaScript** (coming soon) - **Python** (coming soon) ### Automatic target table creation _Expected release: mid July 2025_ Gluesync 2.1 will introduce **automatic target table creation**, simplifying the process of setting up your data integration pipelines. This feature will ensure that target tables are created automatically when needed, reducing the manual setup required and streamlining your workflow. This feature will support all **compatible RDBMS agents, including Oracle, IBM i DB2, and Microsoft SQL Server**. The target table creation process will be based on the source table schema, including column names, data types and constraints. Need to modify the proposed target table create statement? No problem. You’ll be able to edit the proposed statement via our new code editor. _The official documentation will be soon available._ ## Building on Gluesync’s powerful foundation These new features complement the capabilities introduced in previous versions, creating an increasingly comprehensive platform: - [**military-grade security**](https://molo17.com/blog/gluesync-node-to-node-encryption/): advanced node-to-node encryption with AES-256 and Diffie-Hellman key exchange for maximum data protection (since 2.0.6) - [**multilingual support**](https://molo17.com/blog/gluesync-2-0-9-update-multilingual-support-developer-tools-sdks-and-tight-grafana-integration/): interfaces in Italian, Spanish, and Japanese with automatic detection based on browser settings (since 2.0.9) - [**developer SDKs**](https://molo17.com/blog/introducing-gluesync-sdk/): open-source Python and Node.js SDKs for extending platform capabilities and creating custom integrations (since 2.0.9) - [**Modules framework**](https://molo17.com/blog/gluesync-modules/): extensible components that integrate with the Core Hub to provide specialized functionality (since 2.0.9) - [**Bootstrapper**](https://molo17.com/blog/gluesync-bootstrapper-tool/): open-source configuration tool that transforms hours of manual setup into seconds of automated configuration (since 2.0.9) - [**Chronos Scheduler**](https://molo17.com/blog/gluesync-module-chronos-scheduler/): advanced task automation to schedule recurring operations directly from the Gluesync UI (since 2.0.10) ## A continuing commitment to innovation Gluesync 2.1 represents MOLO17’s ongoing dedication to providing the most advanced data integration solutions available. By addressing the organizational challenges that arise in complex data environments, this release helps businesses manage their data pipelines with greater efficiency and control. With Gluesync 2.1, we are addressing the real-world challenges our customers face when managing complex data relationships. The introduction of Groups and Chains, along with User Defined Functions, gives users unprecedented control over their data pipelines, making even the most complex integration scenarios manageable. ## Upgrading to Gluesync 2.1 Existing Gluesync users can upgrade to version 2.1 through their customer portal. New users can sign up for a 30-day trial to experience the powerful capabilities of Gluesync firsthand.
