Pre-handle SSTFiles to DTFiles when applying snapshots (pingcap#1439) (…

…pingcap#1867) * Add `raft.snapshot.method` in configuration file to control the method of applying snapshots - "block" decode snapshot data as a block - "file1" decode snapshot data as DTFiles (directory mode) [**By default**] * Add a stream `SSTFilesToBlockInputStream` to decode snapshot data into blocks * Add a stream `BoundedSSTFilesToBlockInputStream` to bound the blocks read from SSTFilesToBlockInputStream by column `_tidb_rowid` * Add a stream `SSTFilesToDTFilesOutputStream` that accept `BoundedSSTFilesToBlockInputStream` as input stream to write blocks into DTFiles * Make `STORAGE_FORMAT_CURRENT` to be `STORAGE_FORMAT_V2` by default to support ingest DTFile into DT engine * Fix the bug that the block decoded from SSTFile is not sorted by primary key and version (pingcap#1888) * Fix panic with feature compaction filter with DTFile * Fix ingest write amplification after snapshot apply optimization (pingcap#1913) Co-authored-by: Zhigao Tong <[email protected]> Signed-off-by: JaySon-Huang <[email protected]>
