Understanding Amazon CloudSearch Limits
This table shows naming and size restrictions within Amazon CloudSearch. You can submit a request if you need to increase the maximum number of search instances or partitions for a search domain. For information about increasing other limits such as the maximum number of search domains, contact Amazon CloudSearch.
The current Amazon CloudSearch limits are summarized in the following table.
|Batch size||The maximum batch size is 5 MB.|
|Data loading volume||You can load up to 10,000 document batches per day (every 24 hours), with each batch size up to 5 MB. Loading more data per day significantly increases the latency of document updates. To mitigate this risk, you can increase your update capacity by selecting a larger instance type. For more information, see Creating Document Batches.|
