| Add method TSStatus deleteStorageGroups(1:list\<string> storageGroup) | Yi Tao |
* Use struct **TSStatus** to replace all structs with only one field `1: required TS_Status status`, including: ~~TSCloseSessionResp~~ closeSession, ~~TSCancelOperationResp~~ cancelOperation, ~~TSCloseOperationResp~~ closeOperation, ~~TSSetTimeZoneResp~~ setTimeZone.
* Add **TSBatchInsertionReq**, **TSCreateTimeseriesReq**, **TSSetStorageGroupReq** and **TSDeleteReq**.
* Change method name ~~TSExecuteStatementResp executeInsertion(1:TSInsertionReq req)~~ to **TSExecuteStatementResp insert(1:TSInsertionReq req)**, and add method **TSExecuteBatchStatementResp insertBatch(1:TSBatchInsertionReq req)** for batch inserting interface.
## 3. Update
* Add method **TSStatus setStorageGroup(1:TSSetStorageGroupReq req)** and **TSStatus createTimeseries(1:TSCreateTimeseriesReq req)** for creating metadata interface.

| 258 | [IOTDB-143]Development of merge | jt2594838 | Add totalChunkNum and invalidChunkNum to TsFileMetaData. |
| 409 | \[IOTDB-165\]\[TsFile\] Delete a current version and add a number version and an exception. | Genius_pig | (1) Delete a current version in TsFileMetaData; <br/>(2) Change the TsFile magic number from 12 bytes to: 6 bytes magic string ("TsFile") + 6 bytes version number ({"000001", "000002", ""000003"}) ("v0.8.0" is the first version (we treat it as "000000"));<br/>(3) The tail of a TsFile only has "TsFile" magic string, without the version number. |
| 466 | [IOTDB-208] Bloom filter | SilverNarcissus | Add four fields for the bloom filter to TsFileMetaData: 1) bit vector byte array length, 2) bit vector byte array, 3) the number of bits, 4) the number of hash functions. |
