Hi all,
I submitted a PR[1] to support range delete for a timeseries. JIRA issue is [2]. Now the "delete from ..." SQL support specifying a range in the where expression. The where expression may contain Lt/LE, Gt/GE, EQ, AND with two Lt/LE, Gt/GE, EQs. The deletion range is represented by a [startTime, endTime] interval in current implementation. The record format in Mods file has been changed as well. For a deletion SQL: "delete from root.sg.d0.s0 where time <= 100 and time >= 50" Assuming the version number is 10, then it will leave a line "root.sg.d0.s0, 10, 50, 100" in the Mods file. For Mods files with only one "endTime" timestamp in previous version, the query engine will recognize it as having a [0, endtime] deletion range. Please leave your opinions.
