Amazon Connect 分析数据湖中的案例数据

本主题详细介绍了 Amazon Connect 数据湖案例表中的内容。该表列出了内容的列、类型和说明。

有两种方法可以访问分析数据湖和配置要共享的数据：

如果您无法使用选项 1 访问调度表，请尝试使用选项 2。

案例事件

表名：case_events

复合主键：{instance_id, event_id}

示例查询

以下 Athena 中的示例查询创建了一个可扁平化案例事件表中的自定义字段的视图：

CREATE VIEW case_events_flattened AS
SELECT
    ce.event_id,
    ce.case_id,
    ce.event_timestamp,
    ce.event_type,
    ce.instance_id,
    -- ... other system fields
    -- Flattened custom fields
    cf.id AS custom_field_id,
    cf.field_name AS custom_field_name,
    CASE
        WHEN cf.string_value IS NOT NULL THEN 'string'
        WHEN cf.double_value IS NOT NULL THEN 'double'
        WHEN cf.timestamp_value IS NOT NULL THEN 'timestamp'
        WHEN cf.boolean_value IS NOT NULL THEN 'boolean'
        ELSE 'unknown'
    END AS custom_field_type,
    cf.string_value AS custom_field_string_value,
    cf.double_value AS custom_field_double_value,
    -- Cast milliseconds to timestamp
    CAST(from_unixtime(cf.timestamp_value / 1000.0) AS TIMESTAMP) AS custom_field_timestamp_value,
    cf.boolean_value AS custom_field_boolean_value
FROM "case_events resource link table name" ce
CROSS JOIN UNNEST(ce.custom_fields) AS t(cf)

以下示例创建了一个视图，该视图返回每个案例的最新状态：

CREATE OR REPLACE VIEW latest_case_state AS
SELECT *
FROM (
    SELECT *,
        ROW_NUMBER() OVER (
            PARTITION BY case_id, instance_id
            ORDER BY event_timestamp DESC
        ) AS rn
    FROM "case_events resource link table name"
) t
WHERE rn = 1;

案例相关物品事件

表名：case_related_item_events

复合主键：{instance_id, event_id}
