The number of threads to use when selecting data via a parallel scan. Setting ThreadCount to 1 will disable parallel scans.

Data Type

string

Default Value

"4"

Remarks

Parallel scans allow data to be retrieved faster by splitting up the retrieval process across multiple threads. This can greatly improve performance when scanning data in Amazon DynamoDB. However, this will also consume your read units for a table much faster than a single thread. Consider your available cores, bandwidth, and read units for your tables before increasing the ThreadCount.
