Potential bug in Schema Validation

[OfekRonNow]

As far as i understand from source code this is how Schema Validation works (when enabled):

1. there is a setting for the interval of periodic table Schema updates triggers
2. whenever an insert fails (at server side) it will trigger update Schema and retry
3. The scehma validation done on first record, if the validation fails there is no retrying (RuntimeException) and no schema update attempt (only updates on ServerExceptions) whole batch will be moved to DLQ.

So from what i see, there is a potential bug :

Imagine scenario where CH table(CHT) has schema A, and CHConnect(CHC) synced with it. now we change CHT schema to B, CHC hasnt updated yet, B schema data starts arriving and fails validation untill next schema update - which could only be triggered by next periodic update as validation failure blocks insert attempt e.g there will be no ServerException related trigger.

Suggested Fix - try to update schema on validation failures and retry validation before moving to dlq
