TiSpark。本文假设你对 Spark 有基本认知。你可以参阅 <a href="https://spark.apache.org/docs/latest/index.html" target="_blank" referrerpolicy="no-referrer-when-downgrade">Apache Spark 官网</a>了解 Spark 的相关信息。</p><p>TiSpark 深度整合了 Spark Catalyst 引擎，可以对计算进行精确的控制，使 Spark 能够高效地读取 TiKV 中的数据。TiSpark 还提供索引支持，帮助实现高速点查。</p><p>TiSpark 通过将计算下推到 TiKV 中提升了数据查询的效率，减少了 Spark SQL 需要处理的数据量，通过 TiDB 内置的统计信息选择最优的查询计划。</p><p>TiSpark 和 TiDB 可以让用户无需创建和维护 ETL，直接在同一个平台上进行事务和分析两种任务。这简化了系统架构，降低了运维成本。</p><p>用户可以在 TiDB 上使用 Spark 生态圈的多种工具进行数据处理，例如：</p><ul><li>TiSpark：数据分析和 ETL。</li><li>TiKV：数据检索。</li><li>调度系统：生成报表。</li></ul><p>除此之外，TiSpark 还提供了分布式写入 TiKV 的功能。与使用 Spark 结合 JDBC 写入 TiDB 的方式相比，分布式写入 TiKV 能够实现事务（要么全部数据写入成功，要么全部都写入失败）。</p><style data-emotion="css 1weqspv">.css-1weqspv{padding-top:0.5rem;padding-bottom:0.5rem;}.css-1weqspv

datetime、date 或能被解析为 datetime、date 的 string 字面量。</li></ul><p>如果分区裁剪未被应用，TiSpark 将会读取所有分区表。</p><p><strong>写分区表</strong></p><p>目前, TiSpark 仅支持写入 range 与 hash 分区表，且需满足以下任一条件：</p><ul><li>列表达式，如
