This release improves the speed and usability of the initial data load, adds enhanced conflict resolution, and includes support for the Snowflake data warehouse.

A cross-platform initial data load is the first step for replication,” said Josh Hicks, head, sales engineering, “and we wanted the user to have a good first impression with a fast data load that’s easy to track.

A Outgoing Loads screen in the web console shows statistics and visualized progress of the data load, which refreshes in near real-time. Tables are listed across pending, active, and completed panels as their status changes. Active tables show progress bars for extract, transfer, and load phases. At a glance, a time series chart shows performance of the load over time, while a pie chart shows overall completion and estimated time remaining.

I’m always asked about how long a load is going to take, so we built those same calculations into the screen to make it accessible to everyone,” said Hicks.

The speed of the initial data load was improved, with the extraction and bulk load sub-systems receiving performance improvements. The extraction queries were optimized to return data quicker, with data formatting done in parallel at the server process. Oracle and Tibero database dialects received bulk loader support based on their native SQL*Loader and tbLoader bulk loading tools respectively. Extracting large object (LOB) data automatically uses two passes to extract small objects followed by larger ones.

Hicks said: “On projects, we’ve learned to disable or remove constraints on the target database for the fastest possible load of these large databases, so we went ahead and made that into an automatic feature to benefit all customers.

Change data capture was enhanced to automatically resolve constraint violations caused by conflicts. Complex chaining of exceptions are handled during data loading to bring the target database into sync with its source, including exceptions with primary key, unique key, and foreign key violations.

Our design approach has always been to automatically recover from errors, so we enhanced data loading to reach out for missing data or remove blocking rows in order to bring two databases into sync,” said Hicks.

This release includes support for replication into the Snowflake database, a data warehouse gaining popularity for its cloud-based storage and analytics. With the initial data load followed by change data capture from a relational database, SymmetricDS can target data into Snowflake and keep it updated with changes. Bulk loading integrates with Snowflake’s internal storage, Amazon’s S3, or Azure to populate the data warehouse.

The company offers a free, trial download of SymmetricDS Pro to evaluate the data replication software within a test environment. A proof of concept project is available, which includes consulting and support from product experts to demonstrate a working solution.
