Apache HBase Performance Tuning
This document discusses tuning HBase and HDFS for performance and correctness. Some key recommendations include: - Enable HDFS sync on close and sync behind writes for correctness on power failures. - Tune HBase compaction settings like blockingStoreFiles and compactionThreshold based on whether the workload is read-heavy or write-heavy. - Size RegionServer machines based on disk size, heap size,

HBase HUG Presentation: Avoiding Full GCs with MemStore-Local Allocation Buffers
HBase HUG Presentation: Avoiding Full GCs with MemStore-Local Allocation Buffers Todd Lipcon presents a solution to avoid full garbage collections (GCs) in HBase by using MemStore-Local Allocation Buffers (MSLABs). The document outlines that write operations in HBase can cause fragmentation in the old generation heap, leading to long GC pauses. MSLABs address this by allocating each MemStore's dat
