## Table description

The `polkadot.calls` table represents *internal* calls within Substrate extrinsics, including recursive calls from `proxy` and `utility` (batch) pallets, and provides detailed call arguments at each level of the call tree. Unlike the `extrinsics` table which only captures the top-level call, this table exposes the full call hierarchy.

Common queries on the `calls` table will typically filter on `block_time`, `call_section` and `call_method` and extract JSON encoded information in
`data` or `decoded_data`.

## Table Schema

| Column | Type | Description |
| - | - | - |
| `year` | `INTEGER` | Calendar year of the block (partition column) |
| `month` | `INTEGER` | Calendar month of the block (partition column) |
| `call_section` | `VARCHAR` | The pallet (module) of this call (e.g. `Balances`, `Staking`) |
| `call_method` | `VARCHAR` | The method name within the pallet (e.g. `transfer`, `bond`) |
| `block_number` | `BIGINT` | The sequential number of the block containing this call |
| `block_time` | `TIMESTAMP` | The timestamp of the block containing this call |
| `extrinsic_id` | `VARCHAR` | Identifier of the parent extrinsic (format: `blockNumber-extrinsicIndex`) |
| `relay_chain` | `VARCHAR` | Name of the relay chain (e.g. `polkadot`, `kusama`) |
| `para_id` | `BIGINT` | Parachain ID, if this call is on a parachain |
| `id` | `VARCHAR` | Unique identifier for this call |
| `block_hash` | `VARBINARY` | Hash of the block containing this call |
| `extrinsic_hash` | `VARBINARY` | Hash of the parent extrinsic |
| `extrinsic_section` | `VARCHAR` | The pallet of the top-level extrinsic |
| `extrinsic_method` | `VARCHAR` | The method of the top-level extrinsic |
| `call_id` | `VARCHAR` | Identifier for this specific call within the extrinsic |
| `call_index` | `VARBINARY` | Encoded index of the call within the pallet |
| `call_args` | `VARCHAR` | JSON-encoded arguments passed to this call |
| `call_args_def` | `VARCHAR` | JSON-encoded definition/schema of the call arguments |
| `root` | `BOOLEAN` | Whether this is the root (top-level) call in the extrinsic |
| `leaf` | `BOOLEAN` | Whether this is a leaf call with no further nested calls |
| `fee` | `DOUBLE` | Transaction fee paid for this call |
| `weight` | `BIGINT` | Execution weight consumed by this call |
| `signed` | `BOOLEAN` | Whether the parent extrinsic was signed |
| `signer_ss58` | `VARCHAR` | SS58-encoded address of the extrinsic signer |
| `signer_pub_key` | `VARBINARY` | Public key of the extrinsic signer |
| `lifetime` | `VARCHAR` | Validity period of the extrinsic (mortal/immortal era) |
| `updated_at` | `TIMESTAMP` | When this record was last updated in the database |
| `ingested_at` | `TIMESTAMP` | When this record was first ingested into the database |
