Summary: Removed rowCountPercentage check and fixed IUD data load issue Key: CARBONDATA-1213 URL: https://issues.apache.org/jira/browse/CARBONDATA-1213 Project: CarbonData Issue Type: Bug Reporter: Manish Gupta Assignee: Manish Gupta Fix For: 1.2.0 Problems: 1. Row count percentage not required with high cardinality threshold check 2. IUD returning incorrect results in case of update on high cardinality column Analysis: 1. In case a column is identified as high cardinality column still it is not getting converted to no dictionary column because of another parameter check called rowCountPercentage. Default value of rowCountPercentage is 80%. Due to this even though high cardinality column is identified, if it is less than 80% of the total number of rows it will be treated as dictionary column. This can still lead to executor lost failure due to memory constraints. 2. RLE on a column is not being set correctly and due to incorrect code design RLE applicable on a column is decided by a different part of code from the one which is actually applying the RLE on a column. Because of this Footer is getting filled with incorrect RLE information and query is failing. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
