The MaxCompute storage service will gradually upgrade the table bucket storage metadata format (including Hash Clustering and Range Clustering) from August 1st 2023 Beijing time. At that time, Hologres instances earlier than Version 1.3.49 will not be able to correctly parse the new data format .

If you need to query the MaxCompute table that contains Clustering attribute, it is recommended that you upgrade the Hologres instance to V1.3.49 or later as soon as possible. Please use self-service upgrade(Please refer to or join the DingTalk group (number: 32314975) to get technical support.
