Leonard Xu resolved FLINK-36970. -------------------------------- Resolution: Resolved via master: dd865bf440b13b34fde40d4644bad7e517fa70f7 > Merge result of data type BIGINT and DOUBLE should be DOUBLE instead of STRING > ------------------------------------------------------------------------------ > > Key: FLINK-36970 > URL: https://issues.apache.org/jira/browse/FLINK-36970 > Project: Flink > Issue Type: Improvement > Components: Flink CDC > Affects Versions: cdc-3.2.1 > Reporter: Xiao Huang > Assignee: Xiao Huang > Priority: Major > Labels: pull-request-available > Fix For: cdc-3.3.0 > > > In SchemaMergingUtils#getLeastCommonType, the merge result of BIGINT and > DOUBLE is STRING now. > However, considering JSON string, JSON number can be integers or floating > point. Data type of integers can be inferred as BIGINT, and floating point > can be inferred as DOUBLE. So a JSON number field will be inferred as STRING, > which is confusing. -- This message was sent by Atlassian Jira (v8.20.10#820010)
