Guo Heng closed TRAFODION-3236.
-------------------------------
Resolution: Not A Problem
I discussed it with a few colleagues including Kenny. The result of the
discussion is that we agree that the chances of a buffer being too long are
very small, so we don't have to do this.
> The logic for allocating receive buffer is complex and can be optimized

> Key: TRAFODION-3236
> URL: https://issues.apache.org/jira/browse/TRAFODION-3236
> Project: Apache Trafodion
> Issue Type: Improvement
> Components: dtm
> Affects Versions: 2.2.0
> Reporter: Guo Heng
> Assignee: Guo Heng
> Priority: Minor
>
> In the code file:
> [core/sqf/src/tm/tm.cpp|https://github.com/apache/trafodion/pull/1748/commits/be7c999b5cc27c74c5b8004158a2aa18236dd6d9#diff-fc1bfd76bb5a88b2fbcd581c90968da9]
> In the function definition of line 2788, there are two buffer definitions,
> la_recv_buffer and la_recv_buffer_ddl. Maybe we can avoid dynamically
> assigning la_recv_buffer_ddl. It is enough to use only la_recv_buffer, which
> simplifies the logic and reduces the heap pressure.
