public class TestStoreFileWriter extends Object
Store file writer does not do any compaction. Each cell written to either the live or historical file. Regular (i.e., not-raw) scans that reads the latest put cells scans only live files. To ensure the correctness of store file writer, we need to verify that live files includes all live cells. This test indirectly verify this as follows. The test creates two tables, each with one region and one store. The dual file writing (live vs historical) is configured on only one of the tables. The test generates exact set of mutations on both tables. These mutations include all types of cells and these cells are written to multiple files using multiple memstore flushes. After writing all cells, the test first verify that both tables return the same set of cells for regular and raw scans. Then the same verification is done after tables are minor and finally major compacted. The test also verifies that flushes do not generate historical files and the historical files are generated only when historical file generation is enabled (by the config hbase.enable.historical.compaction.files).
