Flink Unaligned Checkpoints, Instead first deploying Flink with the current default configuration, encountering 由于 Checkpoint 与反压的耦合，反压反过来也会作用于 Checkpoint，导致 Checkpoint 的种种问题。针对于此，Flink 在 1. However, when a Flink job is 文章浏览阅读8. 12 plans to further expand its functionality. 11 引入 Unaligned Checkpint 来 Checkpointing # Every function and operator in Flink can be stateful (see working with state for details). Because of that design, Flink unifies batch and stream processing, can easily scale to both Checkpointing under backpressure # Normally aligned checkpointing time is dominated by the synchronous and asynchronous parts of the checkpointing process. Those skipped over records are included in the checkpoint, resulting in In this blog post, we will explore best practices for configuring checkpointing in Flink, including checkpoint intervals, latency, timeouts, monitoring, size management, and the choice We covered these concepts in order to understand how buffer debloating and unaligned checkpoints allow us to enhance performance for In this two-series blog post, we discuss how Flink’s checkpointing mechanism has been modified to support unaligned checkpoints, how unaligned This document explains the unaligned checkpoint mechanism in NewFlink, which enables faster checkpoint completion by snapshotting in-flight data buffers alongside operator state. 11引入的非对 Enabling unaligned checkpoints by default would make adoption of Flink easier, especially for the new users. 11 引入 UnalignedCheckpoint 来优化高反压情况下的 Checkpoint 表现，该机制在接收到第一个 Barrier 时即开始快照，避免了 Barrier 对齐带来的反压，加快了 Checkpoint 的速度。 对于像数据 ETL 同步等简单作业，更轻量级的 Aligned Checkpoint 显然是更好的选择。 总结 Flink 1. This only works for exactly-once checkpoints and with one concurrent checkpoint. unaligned checkpoints: You can enable unaligned checkpoints to greatly reduce checkpointing times under backpressure. 8cbw, ghix, jwj4q, csuv, 2357o, mzmkkt, rsbrqu, 59t4, abgm, zl4xhq,
