NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

为数据工程准备测试数据是一个重大挑战。从生产环境转移数据到测试环境存在风险,因此团队通常依赖于编造数据或合成数据。在本期雷达中,我们探讨了诸如 通过大模型生成合成数据等新方法。但大多数情况下,成本较低的程序生成已经足够用。dbldatagen (Databricks Labs Data Generator) 就是这样一个工具;它是一个用于在 Databricks 环境中生成合成数据的 Python 库,适用于测试、基准测试、演示等多种用途。dbldatagen 可以在短时间内生成规模达数十亿行的合成数据,支持多表、变更数据捕获和合并/连接操作等各种场景。它能够很好地处理 Spark SQL 的基本类型,生成范围和离散值,并应用指定的分布。在 Databricks 生态系统中创建合成数据时,dbldatagen 是一个值得评估的选项。
