For Kinesis and DynamoDB streams, an event source mapping creates an iterator for each shard in the stream and processes items in each ...DynamoDB tables are schemaless, except for the primary key, so the items in a table can all have different attributes, sizes, and data types. The total size of an item is the sum of the lengths of its attribute names and values, plus any applicable overhead as described below. You can use the following guidelines to estimate attribute sizes:This value is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on that table. Use this estimate to measure whether a local secondary index is approaching its size limit.

Item's size is the sum of the attribute names and values. As DynamoDB is using UTF8 encoding, most chars use 1 byte but some less used characters, like language specific, use 2, while emojis can consume up to 4. Numbers use between 2 and 21 bytes. Binary and BinarySets are using 1 byte per 1 byte, obviously. Boolean is also 1 byte.

DynamoDB hash function determines the partition where an item is located; Composite primary key: partition key plus sort key (range attribute) where all items with the same sort key are located together ordered by sort key value; No limit to number of items in a table; Maximum item size is 400 KB20 តុលា 2021 ...
