[BEAM-8335] Implement the StreamingCacheManager
URL: https://github.com/apache/beam/pull/10391
cache_manager.py:
- Add the 'write' method to write an element to the cache
- Refactor the 'source/sink' methods to return a PTransform
- Refactor the 'read' method to return a generator instead of the full
list
- Refactor the ReadCache and WriteCache methods to use the source/sink
methods directly
cache_manager_test.py:
- Refactor to use the new implementations
streaming_cache.py:
- Refactor to implement the CacheManager interface
- Refactor 'Reader' class to take in a list of headers
- Refactor 'read' method to read the headers from the cache
- Refactor the 'reader' method into the 'read_multiple' method to read
multiple PCollections from cache given their headers.
streaming_cache_test.py:
- Refactor to use the new implementations
- Create a new class the "InMemoryCache" that is able to write and read
PCollections directly from memory instead of from file.
pipeline_instrument.py:
- Refactor the _read_cache method to only use the ReadCache method
pipeline_instrument_test.py:
- Create a new class the "InMemoryCache" that is able to write and read
PCollections directly from memory instead of from file.
- Simplify the mock writes and tests to use the InMemoryCache

> URL: https://issues.apache.org/jira/browse/BEAM-8335
> Project: Beam
> Issue Type: Improvement

> Priority: Major
> Time Spent: 48h 20m

>
> This issue tracks the work items to introduce streaming support to the
> Interactive Beam experience. This will allow users to:
> * Write and run a streaming job in IPython
> * Automatically cache records from unbounded sources
> * Add a replay experience that replays all cached records to simulate the
> original pipeline execution
> * Add controls to play/pause/stop/step individual elements from the cached
> records
> * Add ability to inspect/visualize unbounded PCollections
