Hey, Recently we saw very high disk usage for some of our hosts. On investigating, we found in our servers, directories something like this for a table:

_tmp/tmp-<segment_name>-<timestamp>/tmp-<uuid>

The segment name in this path^ does not exist anymore for that table (deleted by retention). The contents of the directory are of this manner:

0	col1.sv.sorted.fwd
0	col2.mv.fwd
0	col3.sv.sorted.fwd
0	col4.sv.sorted.fwd
0	col5.sv.sorted.fwd
0	col6.sv.sorted.fwd
4.0K	col1.dict
4.0K	col2.dict
4.0K	col3.dict
26G	    col4.dict
132G	col5.dict
148G	col6.dict

Any idea what this

_tmp

folder signifies and why are they getting created?

@Jackie are you aware of this?

This should be the temporary folder for the consuming segments. Seems like it is not cleaned up properly

Sure
