Enum CellOperation 

pub enum CellOperation {
    Write {
        column: String,
        value: Value,
    },
    WriteWithTtl {
        column: String,
        value: Value,
        ttl_seconds: u32,
    },
    Delete {
        column: String,
    },
    DeleteRow,
}

Operations that can be applied to individual cells within a row.

Per-Cell TTL

Per-cell TTL is supported via the WriteWithTtl variant when using the JSON mutation format directly. CQL syntax (USING TTL) applies TTL uniformly to all cells in a statement. To set different TTLs per column, submit separate mutations or use JSON mutations with WriteWithTtl:

{"WriteWithTtl": {"column": "session_token", "value": {"Text": "abc"}, "ttl_seconds": 3600}}

Variants

Write

Write a value to a column

Fields

column: String

Column name

value: Value

Column value

WriteWithTtl

Write a value to a column with TTL (expiring cell).

The cell will expire after ttl_seconds seconds. This is the only way to set per-column TTL — CQL USING TTL applies to all cells in a statement. Use JSON mutations to set different TTLs per column.

Fields

column: String

Column name

value: Value

Column value

ttl_seconds: u32

Time-to-live in seconds

Delete

Delete a specific column

Fields

column: String

Column name

DeleteRow

Delete entire row (row tombstone)
