PR Summary

• Enhanced Payload Management: The way we manage data (payload) has been refined to keep track of state rows in addition to regular rows. This adds more precision to our data handling.
• Adaptable Empty Block Creation: Making empty blocks is now more flexible as it can work with an optional parameter, 'fake_rows'. This allows us to create blocks populated with default values if needed.
• Consistency in Payload Flushing: Payload flushing, the process of cleaning out data, has been made more consistent by uniformly passing 'None' to an associated function 'empty_block()'.
• Block Pushing Streamlined: The process of pushing empty blocks to a collection (vector) has been simplified by removing unnecessary conditions, leading to cleaner code.
• Inclusion of Empty Block Checks: New checks have been added to correctly handle data situations where a block might be empty, ensuring accurate data management.
• Extended Tracking for Aggregate Metadata: A new tracking field 'is_empty' has been introduced to the metadata of aggregate data to record whether a block of data is empty. This contributes to more granular data tracking.
• Serialization Strategy Refresh: The process of converting data into a stable format (serialization) has been updated to make sure there's always at least one block returned. To do this, it uses the aforementioned 'is_empty' state.
• Intersection Check for Zero-Length Blocks: To avoid unnecessary computing, added a check that will dismiss processing blocks if they have zero-length.
• Early Exit for Transformations with Empty Input: Implemented a feature where further processing is prevented if the input for a transformation is empty. This helps avoid computational resources on trivial cases.
• Test Scripts Added: Introducing new testing tools. A test script called '20_0022_agg_memory.sh' is added which tests memory usage and its results are stored in '20_0022_agg_memory.result'.
