## Proposed changes `DeltaWriterV2` are shared among sinks (OlapTableSinks). After #30098, sinks who complete first will not wait for stream close. They will also not waiting for `DeltaWriterV2` close. Use-after-free may happen because `DeltaWriterV2` and its components are referencing `TupleDescriptor` and `SlotDescriptor` by raw pointer, Since `TupleDescriptor` and `SlotDescriptor` are part of `OlapTableSchemaParam` from a sink. This PR changes `OlapTableSchemaParam` passed to `DeltaWriterV2` to be a shared pointer. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
