Cassandra LCS and STCS compaction strategy explanation

• LCS (Leveled Compaction Strategy) is best for write-heavy workloads with high write throughput and low read latency.

• STCS (Size-Tiered Compaction Strategy) is best for read-heavy workloads with low write throughput and high read latency.

• LCS uses multiple levels of SSTables to reduce read amplification and improve compaction performance.

• STCS merges SSTables based on their size, resulting in fewer but larger SSTables.

• Choosing...read more

Anti-entropy repair is a process in Cassandra that compares data between replicas and repairs inconsistencies.

• Anti-entropy repair is triggered by a read repair or a hinted handoff.

• During anti-entropy repair, Cassandra compares data between replicas and repairs inconsistencies.

• Anti-entropy repair can be performed on a per-column family basis or on the entire keyspace.

• Cassandra uses Merkle trees to detect inconsistencies during anti-entropy repair.

Product lifecycle refers to the stages a product goes through from introduction to withdrawal from the market.
