In my understanding: skipListSizeLimit: It means how many entries can be added in a `EntryMemTable`. Entries will be cached in heap memory first, then async flush into disk. skipListArenaChunkSize: It means the memory size of a `Chunk`(a heap memory pool, to avoid frequently memory allocation and a lot of memory fragments). When bookie received an entry, the entry exists in direct memory, so that it needs to copy into heap memory(`Chunk`). skipListArenaMaxAllocSize: It means the threshold of an entry can be copied into `Chunk`. If an entry's size is greater than `skipListArenaMaxAllocSize`, bookie will be allocated heap memory by invoke `new byte[size]` directly. -- This is an automated message from the Apache Git Service.
