*Optimization Proposal* In Kylin, the index storage is in Parquet format. When querying, if Spark reads Parquet data, it needs to read the Footer information first. In cases where there are many columns, reading the Footer can consume a considerable amount of time. Therefore, caching the Footer information can improve query performance. -- This message was sent by Atlassian Jira (v8.20.10#820010)
