Struct IngestOptions 

pub struct IngestOptions {
    pub table: String,
    pub mode: String,
    pub schema_override: Option<Map<String, Value>>,
    pub merge_key: Option<Vec<String>>,
    pub target_db: Option<String>,
}

Controls how data is loaded into a target table.

Fields

table: String

mode: String

"replace" drops the existing table first; "append" adds rows to it; "merge" upserts rows by Self::merge_key.

schema_override: Option<Map<String, Value>>

When set, bypasses schema inference and uses these exact column types.

merge_key: Option<Vec<String>>

When mode == "merge", the column(s) to match on for upsert. Required in merge mode; rejected in any other mode (the per-call site validates up-front so the lower ingest paths can stay format-agnostic).

target_db: Option<String>

Resolved database alias for fully-qualified SQL. None means the primary (ephemeral); Some("persistent") or Some("user_alias") qualifies table references as "<db>"."public"."<table>". Must be pre-resolved via Engine::resolve_target_db before setting.
