This article explains Apache Hudi’s write‑side indexing, detailing the indexing API, various index types—including simple, Bloom, bucket, HBase, and record‑level indexes—and their mechanisms, helping readers understand how Hudi validates record existence and optimizes updates and deletions.
This article examines the challenges of using Apache Hudi for real‑time data lake writes, analyzes the COW and MOR write models, and presents a custom master‑worker architecture with index optimization and repartitioning that reduces write resource consumption by over 85% while boosting throughput up to 300‑fold.
This guide details practical server‑side and client‑side techniques for improving HBase read and write throughput, covering rowkey design, BlockCache configuration, HFile management, compaction tuning, scan cache sizing, bulkload usage, WAL policies, and SSD storage options.
