The key column in previous downsample query result is confusing. It refers to the start of a window in such results, while user would assume it is a key for a record.

Also, user should be able to slice windows based on queried data, instead of specifying key range.

fix
Add two columns: window_start and window_end to avoid misunderstanding.
Adjust downsample sql statement
SQL adjust
Allow user to use:

SELECT <expression> (, <expression>)* FROM prefixPath <whereClause>? <downsamplingClause>?
<downsamplingClause>: OVER WINDOW LEFT_BRACKET SIZE DURATION (IN <timeInterval>)? (SLIDE DURATION)? RIGHT_BRACKET;
to generate windows according to queried data.

配置方法
Mongodb 使用 uri 对连接参数进行详细配置,包括鉴权机制,相关语法参见 Mongodb 文档

Redis 使用 username 和 password 两个参数配置用户名和参数,若不设置该选项,则不使用鉴权。
What's wrong?
[Relational storage engine] Querying non-existing path prefix in dummy relational engine would cause exception, because the engine tries to connect to a database that does not exist.

Fix
Query infomation about databases before making connection.
This reverts commit 7832a82.
IGinX-THU#398)

User can alter the params of read-only dummy storage engine. The HAS_DATA & IS_READ_ONLY attributes cannot be modified.

SQL
ALTER STORAGEENGINE <engine_id> WITH PARAMS "(<param_key>:<param_value>,?)+";
example:
alter storageengine 2 with params "dummy_dir:test/new_data";

——简化实现,后续随节点移除、容错能力的增强,需要相应调整实现

同时,按需相应调整测试脚本目录结构
