SQLite mirror for PDI_PLTM and CMPT_PL_TRACKMAP.
|
|
|
|
On startup (and on demand) the service pulls all rows from Oracle and
|
|
upserts them into a local SQLite file (hefa_l2.db).
|
|
|
|
Whenever the FastAPI endpoints write to Oracle they also call the
|
|
corresponding sqlite_* helper here so the two databases stay in sync.
