…he#36345) ## Proposed changes Issue Number: close #xxx there's a caller used `getPartitionExprs` and modified the result. the result is a reference to a part of metadata. If when we create the table, the number of editlog didn't reach the limit to generate image file, when it reaches, the image will get the wrong metadata of `partitionExprs` from memory which was modified. currently we don't know why, but this root cause has been confirmed by: ```java private void analyzerPartitionExpr(Analyzer analyzer, PartitionInfo partitionInfo) throws AnalysisException { ArrayList<Expr> exprs = partitionInfo.getPartitionExprs(); for (Expr e : exprs) { LOG.info("beforeB: {}", e.toSql()); e.analyze(analyzer); LOG.info("afterB: {}", e.toSql()); } } ``` ```log 2024-06-18 21:49:07,449 INFO (mysql-nio-pool-154|695) [OlapScanNode.analyzerPartitionExpr():1561] beforeB: date_trunc(Carding_Day, 'MONTH') 2024-06-18 21:49:07,449 INFO (mysql-nio-pool-154|695) [OlapScanNode.analyzerPartitionExpr():1563] afterB: date_trunc(`a`.null, 'MONTH') ```
