| contract_id | Soroban contract id | string | | | Yes | Cluster | Yes | |
| contract_key_type | Contract key type which is an ScVal that can have the following values | string | | | | | | |
| contract_durability | Contract can either be temporary or persistent | string | | | | | | |
| asset_code | The 4 or 12 character code representation of the asset on the network. | string | | | | | | |
| asset_issuer | The account address of the original asset issuer that created the asset. | string | | | | | | |

| balance_holder | The address/account that holds the balance of the asset in contract data | string | | | | | | |
| balance | The number of units of XLM held by the account | string | | | | | | |
| last_modified_ledger | The ledger sequence number when the ledger entry (this unique signer for the account) was modified. Deletions do not count as a modification and will report the prior modification sequence number | integer | | | Yes | Cluster | Yes | |
| ledger_entry_change | Code that describes the ledger entry change type that was applied to the ledger entry. | integer | | | | | Yes | |
| deleted | Indicates whether the ledger entry (balance id) has been deleted or not. Once an entry is deleted, it cannot be recovered. | boolean | | | | | Yes | |
| batch_id | String representation of the run id for a given DAG in Airflow. Takes the form of "scheduled__<batch_end_date>-<dag_alias>". Batch ids are unique to the batch and help with monitoring and rerun capabilities | string | | | | | Yes | |
| batch_run_date | The start date for the batch interval. When taken with the date in the batch_id, the date represents the interval of ledgers processed. The batch run date can be seen as a proxy of closed_at for a ledger. | datetime | | | | | Yes | |
