New Features

👨‍💻 UDFs

User Defined Functions (UDFs) allow you to implement custom business logic and transformations on your data as it flows through the system. UDFs are written in Java, with Kotlin, Python and JavaScript support to come.

UDFs are trigger on the main events that occur on your datasource (e.g. insert, update, delete) and allow you to implement custom business logic and transformations on your data as it flows through the system, also by switching the operation mode based on your business requirements.

You can learn more about UDFs here.

🪓 TRUNCATE operations

TRUNCATE operations are now available in Gluesync for supported agents.

TRUNCATE before Snapshot can be executed before the execution of a snapshot task, to be choosed on a per-snapshot basis from the entity’s play tab.

TRUNCATE command forwarding (enabled by default) can be disabled at agent’s level to avoid unwanted behaviors. With this feature enabled, TRUNCATE operations executed on supported source databases are automatically forwarded to supported target databases.

New Features

⛓️ Groups & Chains

Groups and Chains transform how you organize and manage your data entities, making complex data integration scenarios more manageable and intuitive.

While Groups serve as a logical grouping mechanism for entities, designed to simplify configuration and settings management across multiple related entities, Chains define a physical execution order allowing for referential integrity among tables.
