suyue closed IOTDB-160. ----------------------- > External sort in non-sequential data > ------------------------------------ > > Key: IOTDB-160 > URL: https://issues.apache.org/jira/browse/IOTDB-160 > Project: Apache IoTDB > Issue Type: Improvement > Reporter: suyue > Priority: Major > Labels: pull-request-available > Time Spent: 20m > Remaining Estimate: 0h > > For the query of non-sequential data, each chunk is constructed separately as > reader, then merged and sorted. When non-sequential data is large, so the > number of chunks of merge is too large, it may cause the problem of > exhausting memory. So when the number of chunks merged at the same time > reaches a certain limit, the external method is adopted. -- This message was sent by Atlassian Jira (v8.3.4#803005)
