[fsanaulla]

implement InfluxRDD as a main abstraction

[lukaszdudek-silvair]

How much work there is to enable this? Do you have any specific tasks planned?

[fsanaulla]

In the research stage, plan to implement it as a next feature.
The main challenge is correctly defined partitioning. I'll update about the progress.

Need to be done before:

• CORE: readUnsafe method and optimize generated code chronicler#153
• URL: move to request-scala chronicler#154
• URL: experimental streaming support chronicler#142
• ALL: data compression chronicler#157
• ALL: charset param for incomming data in write chronicler#158

[fsanaulla]

All required changes are implemented in core. I'll start working on it.

Separate HTTP RDD was implemented as a separate project, I'll integrate it as a separate module
