Dynamodb sort by date

  • Dec 13, 2017 · If you store your dates / timestamps in Epoch format, you should use Number. String. DynamoDB collates and compares strings using the bytes of the underlying UTF-8 string encoding. For example, “a” (0x61) is greater than “A” (0x41), and “¿” (0xC2BF) is greater than “z” (0x7A). You can use the string data type to represent a date or a time stamp. One way to do this is by using ISO 8601 strings, as shown in these examples: 2016-02-15; 2015-12-21T17:42:34Z< 20150311T122706Z; Number

  • Query results are always sorted by the sort key (ascending for both numbers and string by default). To reverse the sort order set the ScanIndexForward parameter to false; By Default Queries are going to be Eventually consistent but can be changed to StronglyConsistent. DynamoDB scans Scan operation examines every item.
  • Original Answer: DynamoDB does not allow indexed lookups on the range key only. The hash key is required such that the service knows which partition to look in to find the data. You can of course perform a scan operation to filter by the date value, however this would require a full table scan, so it is not ideal.
  • DynamoDB Streams data retention limit. DynamoDB Streams have a retention period of 24 hours. Change records exist in the stream for one day and are then deleted.

  • What I mean is, that while the primary or sort key can be duplicated, you cannot duplicate the primary and sort key within the table. This should start to hint at how important data modeling is when using DynamoDB or any other NoSQL system. 但DynamoDb实际上使用与mongodb 有很大差异,这里自己用到一些操作方式(查询 更新 批量删除)做一些说明。 DynamoDB 中绝大部分操作都与主键有关。 PS:DynamoDB 不支持date类型,我们以unix时间戳形式存储date。
