Description
Using latest 2.0 beta, create a cube with TopN, but specifying using non-dict encoding, the JSON is like:
{
"name": "TOP_CUSTOMER",
"function": {
"expression": "TOP_N",
"parameter": {
"type": "column",
"value": "P_LINEORDER.V_REVENUE",
"next_parameter": {
"type": "column",
"value": "P_LINEORDER.LO_CUSTKEY"
}
},
"returntype": "topn(100,4)",
"configuration": {
"topn.encoding.P_LINEORDER.LO_CUSTKEY": "integer:4",
"topn.encoding_version.P_LINEORDER.LO_CUSTKEY": "1"
}
}
But, in the third step "Extract Fact Table Distinct Columns", there is still a reducer running for "P_LINEORDER.LO_CUSTKEY"; as this column is a UHC, it takes a long time and finally got failed.
Expected behavior: no reducer for this column. 1.6.0 doesn't have this issue; this is a new issue in 2.0 during the upgrade to snowflake.
