With the revert of b84f462 by ccf25df, we lost an extra benefit that was included in the reverted commit: a fix for the fact that
IcebergCatalogHandlerWrapper
does not always close its underlyingCatalog
, thus relying onCallContext
to play the role of the "sweeper car" and close everything that was left unclosed at the end of the request processing.This PR re-applies that fix again.
If this change gets accepted, we could envisage removing
CallContext.closeables()
– as the main purpose of this method is to close unclosed catalogs.
