Docker compose kits

  • For Windows users, the kit has now been updated to use the same volume mount as Linux users, simplifying the folder structure and making it easier to upgrade;

  • Linux users are shifting towards the new fixed versions tag (e.g. 2.1.8.0, always fetched from our version control system at the moment the kit is baked) instead of relying on the latest tag, this will make it easier to upgrade via Conductor and the new modules manager;

New Features

🪄 Conductor & Modules manager: update Gluesync from the GUI

Two weeks ago we released the first version of the Conductor module, which allows you to manage your agents right from the UI. We’re keeping up adding new functionalites around this module; with this new release we’re adding the ability to update existing modules: the platform will automatically fetch for updates and notify you when a new version is available, additinoally you can manually update modules from the UI by going to the modules manager section and clicking the update button.

Please note that the Conductor module is currently available for Linux users only.

Release Highlights 🌟

New Features

🏗️ Target table creation

Through the Target table creation you can now finally be able to create tables in your target database.

Gluesync will provide you with a wizard to help you create tables in your target database, displaying the SQL statement that will be executed to create the table for you to review, edit and execute.

You can learn more about the target table creation here.

🧩 Parquet files support

A long awaited feature: you can now store your data to Parquet files for AWSS3, Azure Data Lake Gen 2 and Google Cloud Storage.

Gluesync will provide you with a new default target type for your replication tasks: Parquet files. Parquet files are a columnar storage file format that is optimized for performance and is used by many big data processing frameworks such as Apache Spark. This allows you to feed your data into big data processing frameworks and perform complex data analysis and machine learning tasks.

You can still use the old target types (JSON), by setting the target type to JSON in the entity’s settings.

You can learn more about the parquet files support here.

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.

You can learn more about Groups and Chains here.
