-----------------------------
Summary: Add iterators to TVList to prevent data copy
Key: IOTDB-433
URL: https://issues.apache.org/jira/browse/IOTDB-433
Project: Apache IoTDB
Issue Type: Improvement
Reporter: atoildw
Assignee: atoildw
Fix For: 0.10.0-SNAPSHOT
In the previous design, when you used in-memory data:
# the {{TVList}} structure was {{clone}} into an {{IWritableMemChunk}} named
{{chunkCopy}}
# And then copied again into a {{List<TimeValuePair>}} structure
# If multiple data happens to exist in {{flushingMemTable}},
{{MemSeriesLazyMerger}} will use {{addAll(List<TimeValuePair>)}} to copy again
so, I think we should directly use {{TVList}} to implement {{IPointReader}}
interface and use it externally
Add the {{Iterator}} class and {{getIterator}} method for {{TVlist}}
and then ,data was copied only when it is used
