    For batch ingestion, we want to maximize throughput by minimizing the number of incremental persists. The limit here is really a safety: in case we have a large number of very small rows, we don't want to get overwhelmed by per-row overheads. Mostly, we rely on the bytes limit getMaxBytesInMemory().

    Constant Field Values
  - DEFAULT_MAX_ROWS_IN_MEMORY_REALTIME
```
static final int DEFAULT_MAX_ROWS_IN_MEMORY_REALTIME
```
    For realtime ingestion, we want to balance ingestion throughput and query performance. Since queries on in-memory data are slower due to using IncrementalIndex instead of QueryableIndex, we cap the row count of in-memory data.
