IBroadcastableClusterInfo (cassandra-analytics-core 0.2.0 API)

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

BroadcastableClusterInfo, BroadcastableClusterInfoGroup
```
public interface IBroadcastableClusterInfo
extends java.io.Serializable
```
Minimal interface for cluster information that can be safely broadcast to Spark executors. This interface contains only the essential methods that broadcastable cluster info implementations (BroadcastableClusterInfo, BroadcastableClusterInfoGroup) need to provide.
Unlike ClusterInfo, this interface doesn't include methods that require fresh data from Cassandra Sidecar or runtime operations. These implementations are designed to be broadcast and then reconstructed to full ClusterInfo instances on executors.
Methods in this interface:
- getPartitioner() - static cluster partitioner configuration
- getLowestCassandraVersion() - pre-computed version string
- clusterId() - cluster identifier (optional)
- getConf() - BulkSparkConf needed for reconstruction on executors
- reconstruct() - reconstructs full ClusterInfo instance on executors

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.lang.String`	`clusterId()`	ID string that can uniquely identify a cluster.
`BulkSparkConf`	`getConf()`
`java.lang.String`	`getLowestCassandraVersion()`
`org.apache.cassandra.spark.data.partitioner.Partitioner`	`getPartitioner()`
`ClusterInfo`	`reconstruct()`	Reconstructs a full ClusterInfo instance from this broadcastable data on executors.

- Method Detail
  - getPartitioner
```
org.apache.cassandra.spark.data.partitioner.Partitioner getPartitioner()
```
    Returns:
    
    the partitioner used by the cluster
  - getLowestCassandraVersion
```
java.lang.String getLowestCassandraVersion()
```
    Returns:
    
    the lowest Cassandra version in the cluster
  - clusterId
```
@Nullable
java.lang.String clusterId()
```
    ID string that can uniquely identify a cluster. When writing to a single cluster, this may be null. When in coordinated write mode (writing to multiple clusters), this must return a unique string.
    
    Returns:
    
    cluster id string, null if absent
  - getConf
```
@NotNull
BulkSparkConf getConf()
```
    Returns:
    
    the BulkSparkConf configuration needed to reconstruct ClusterInfo on executors
  - reconstruct
```
ClusterInfo reconstruct()
```
    Reconstructs a full ClusterInfo instance from this broadcastable data on executors. Each implementation knows how to reconstruct itself into the appropriate ClusterInfo type. This allows adding new broadcastable types without modifying the reconstruction logic in AbstractBulkWriterContext.
    
    Returns:
    
    reconstructed ClusterInfo (CassandraClusterInfo or CassandraClusterInfoGroup)
