SymmetricDS 3.10 was released, which includes 30 improvements, 5 new features, and 15 bug fixes!
Here are some highlights:
Initial Loads
- New sym_table_reload_status table tracks progress and statistics of loads by their ID
- Queuing the load is faster using estimated row counts of tables
- Extracting data is faster by eliminating SQL functions and formatting data in code
- When loading multiple nodes, extracts are shared so common tables are only extracted once
- Oracle/Tibero use two passes on tables with LOBs to optimize extraction under 4k limit
- Loading is faster by deferring indexes and foreign key creation until the end of the load
- New bulk loader support for Oracle (SQL*Loader) and Tibero (tbLoader)
- Auto resolution of foreign key errors due to extracts running at different times on busy system
Change Data Capture
- Enhanced fallback operations can now deal with chained foreign key and unique key exceptions
- Faster insert performance on Postgres 9.5 using “on conflict” clause to detect conflicts
- Oracle/Tibero LOBs optimized automatically for routing and extraction under 4k limit
- Faster, more aggressive purge settings to keep system overall running better
Databases
- Snowflake database as a load-only target with bulk loading
See the change log for more details.
