BigTableStorage

java.lang.Object
- cz.o2.proxima.direct.io.bigtable.BigTableStorage

All Implemented Interfaces:

AbstractDataAccessorFactory<DirectDataOperator,DataAccessor>, DataAccessorFactory, java.io.Serializable
```
@AutoService(DataAccessorFactory.class)
public class BigTableStorage
extends java.lang.Object
implements DataAccessorFactory
```
Storage descriptor for bigtable:// URIs.
BigTable storage uses URIs in the form of bigtable://<project>:<instance>/<table>?family=<family> and stores data using HBase client in BigTable instance instance of project project in table named table in family family.
An optional parameter in URI called v can be used to distinguish two serialization versions of data in BigTable cell:
1. v=1 (default) stores the serialized bytes of a value in a cell directly
2. v=2 uses protobuffer to store more metadata into the value
The v=2 serialization format is required to support transactions on top of BigTable, because the metadata preserves sequentialId (stored in StreamElement#getSequentialId).
