| Table Name | Table Name | The name of the Accumulo Table into which data will be placed Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables) | ||
| Create Table | Create Table | False |
| Creates a table if it does not exist. This property will only be used when EL is not present in 'Table Name' |
| Threads | Threads | 10 | Number of threads used for reading and writing | |

| End key | end-key | End row key for this. If not specified or empty this will be infinite Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables) | ||
