Feature Improvement

Improved job‑A: the system now provides a reason after a job dies, adding a prompt when the DTLE API reports a dead job.

Bug Fixes

Table name case problem #441‑1 – fixed errors caused by automatic conversion to lowercase.

Use mapping job.json failed when testing increment, the job is 'complete' #447 – resolved the 'complete' status issue during mapping incremental tests.

After job creation, inserting data to null schema in source caused DTLE panic #450 – fixed panic when inserting empty data into source.

Mapping: after renaming, deleting source table, destination table not deleted #453 – ensured destination tables are removed when source tables are deleted after a rename.

Docker run failed to start #454 – resolved Docker startup failure.

Kafka: unknown table structure #459 – fixed errors when Kafka encounters unknown table structures during transfer.

DTLE 2.19.05.0 is an optimization release that addresses a batch of bugs and introduces minor usability enhancements.
