DynamoDB allows for specification of secondary indexes to aid in this sort of query. Secondary indexes can either be global, meaning that the index spans the whole table across hash keys, or local meaning that the index would exist within each hash key partition, thus requiring the hash key to also be specified when making the query. Required: No. A Timestamp, Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. When the number of (mode, counter) pairs reaches a threshold (say 15), the oldest pair is removed from the clock. This blog post introduces Amazon DynamoDB to Cassandra developers and helps you get started with DynamoDB by showing some basic operations in Cassandra, and using AWS CLI to perform the same operations in DynamoDB. A problem with defining a complete custom format specifier that includes the millisecond component of a date and time is that it defines a hard-coded format that may not correspond to the arrangement of time elements in the application's current culture. A question I see over and over again is how do you store your dates or timestamps. There’s no MILLISECOND equivalent to the SECOND function and you will not find a predefined time format that includes hours, minutes, seconds and milliseconds.. The Unix timestamp (also known as Epoch time, POSIX time), it is the number of seconds elapsed since January 1970 00:00:00 UTC.
