1. What is the maximum number of transactions per second (TPS) an OpenSearch Domain and Index can handle?
2. What is the maximum size of an individual record (row) in OpenSearch?
3. What is the maximum size of an individual feature (column) in OpenSearch?
4. What is the maximum number of columns in an OpenSearch Index (table)?
5. What is the maximum number of columns you can query at once in an OpenSearch Index?
6. Does AWS OpenSearch charge for read and write queries? How much?

Use the following formula to calculate the maximum active threads for search requests:

int ((# of available_processors * 3) / 2) + 1

Use the following formula to calculate maximum active threads for write requests:

int (# of available_processors)
