v2.1.5

Do not report an error or exit when a Tombstone store exists in the cluster #4223

v2.1.4

• Added an option to disable periodic Level-1 compaction. When the TiKV cluster is 2.1.4 or above, Level-1 compaction is performed automatically even during import mode, and thus should be turned off on Lightning's side (#119, tikv/tikv#4086)
• Limited the number of engines queued for import, to avoid overflowing Importer's hard disk space (#119).

v2.1.3

• Open sourced (#116, #123)
• Improved memory use and performance when parsing the SQL dump (#107, #108).
• Lightning no longer splits a data file into multiple chunks, which eliminates time wasted on parsing every file twice (#109).
• Limited I/O concurrency to avoid performance drop caused by cache miss (#110)
• Implemented "batching" for partially ingest a large table into TiDB. This should improve stability of the import process (#113)
• Fixed the issue where the imported data was not evenly distributed (tikv/tikv#4056)
