To speed up migration process and synchronization process for large databases or for rational memory consumption Bulk Insert and Quantization features have been implemented. You can turn them on and off at the customization stage.
If your data migration process is time-critical, it takes less time to convert data with checked Bulk Insert option. Bulk Insert feature inserts bunch of several records to a target database at a time that speeds up a whole database migration significantly.
"Timeout Expired" error. “Out of memory for query result” error. “Query Result Set too Large” error.
-Pay an attention that Sync tools do not support Bulk Insert. Converters support both Quantization and Bulk Insert options.
-The dbs structures should contain an Unique or Primary index, not a composite one.
