| ledger_key_hash | Either contract_id or contract_code_hash | string | | Yes | |
| ledger_entry_type | The type ledger entry for data stored such as contract data or liquidity pools | string | | Yes | |
| 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 | |
| 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 | |
| batch_insert_ts | The timestamp in UTC when a batch of records was inserted into the database. This field can help identify if a batch executed in real time or as part of a backfill | timestamp | | Yes | |
| closed_at | Timestamp in UTC when this ledger closed and committed to the network. Ledgers are expected to close ~every 5 seconds | timestamp | | Yes | |
| ledger_sequence | The sequence number of this ledger. It represents the order of the ledger within the Stellar blockchain. Each ledger has a unique sequence number that increments with every new ledger, ensuring that ledgers are processed in the correct order. | integer | | Yes | |
