Default grouping Strategy the last Level of the Persistent configuration.
Default grouping Strategy the last Level of the Persistent configuration. It uses 3 three compression types with minimum compression requirement of 10%.
All there compression libraries are used and compressions are executed in their order until a successful compression is achieved. 1. LZ4's fastest Java instance with Fast compressor and decompressor. 2. Snappy 3. UnCompressedGroup - No compression, key-values are just grouped.
After key-values are Grouped, the Groups can also be grouped which will result in nested Groups. Although nested Groups can give high compression but they it can also have . Either GroupGroupingStrategy.Count or GroupGroupingStrategy.Size can be used check documentation on the website for more info.
By default currently nested Group compression is not used because the default file sizes are too small (2.mb) to be creating nested Groups.
