Block.getLogicalSizeInBytes介绍

[英]Returns the size of the block contents, regardless of internal representation. The same logical data values should always have the same size, no matter what block type is used or how they are represented within a specific block.

This can differ substantially from #getSizeInBytes for certain block types. For RLE, it will be N times larger. For dictionary, it will be larger based on how many times dictionary entries are reused.
[中]返回块内容的大小，而不考虑内部表示形式。相同的逻辑数据值应始终具有相同的大小，无论使用什么块类型或它们在特定块中如何表示。
对于某些块类型，这可能与#getSizeInBytes有很大不同。对于RLE，它将是N倍大。对于字典，它将根据字典条目被重用的次数而变大。
