Pick a partition count for a partitioned cache on Apache Ignite 2 or GridGain 8. Default is 1024. This guide covers when to accept it, when to size up, and the formula that maps cache row count to a safe partition number.
Diagnose and fix a hot partition on Apache Ignite 2 or GridGain 8. Three-step procedure identifies the partition, its owner, and the skew pattern. Matched fixes cover salting, affinity-field changes, cache-level overrides, schema redesign, and replication.
Watch a cache spread 10,000 entries across three nodes and then four. Use the Affinity API to see which node owns each key, learn the vocabulary of partitions and primaries, and establish the mental model every cache user needs.
