------------------------------------
Summary: Add RowBatchQueue interface with an implementation backed
by a std::queue
Key: IMPALA-8779
URL: https://issues.apache.org/jira/browse/IMPALA-8779
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Sahil Takiar
Assignee: Sahil Takiar
Add a {{RowBatchQueue}} interface with an implementation backed by a
{{std::queue}}. Introducing a generic queue that can buffer {{RowBatch}}es will
help with the implementation of {{BufferedTupleSink}}. Rather than tie the
{{BufferedTupleSink}} to a specific method of queuing row batches, we can use
an interface. In future patches, a {{RowBatchQueue}} backed by a
{{BufferedTupleStream}} can easily be switched out in {{BufferedTupleSink}}.
We should consider re-factoring the existing {{RowBatchQueue}} to use the new
interface as well.
