类 LayeredHTable

java.lang.Object

org.apache.hadoop.hbase.client.HTable

org.apache.hadoop.hbase.client.LayeredHTable

所有已实现的接口:

Closeable, AutoCloseable, Table

直接已知子类:

ColdHTable, HotHTable

@InterfaceAudience.Private
 @InterfaceStability.Stable
public abstract class LayeredHTable
extends HTable

LayeredHTable is used to read data of layered hot/cold table. when reading hot table, cold data will be filtered. when reading cold table, cold data in hot table will be read and merged.

LayeredHTable

@InterfaceAudience.Private
protected LayeredHTable(ClusterConnection connection,
                                                   org.apache.hadoop.hbase.client.TableBuilderBase builder,
                                                   RpcRetryingCallerFactory rpcCallerFactory,
                                                   RpcControllerFactory rpcControllerFactory,
                                                   ExecutorService pool)

Creates an object to access a HBase table. Used by HBase internally. DO NOT USE. See ConnectionFactory class comment for how to get a Table instance (use Table instead of LayeredHTable).

参数:

connection - Connection to be used.

builder - The table builder

rpcCallerFactory - The RPC caller factory

rpcControllerFactory - The RPC controller factory

pool - ExecutorService to be used.
