BaseTable

java.lang.Object
- org.apache.iceberg.BaseTable

All Implemented Interfaces:

java.io.Serializable, HasTableOperations, Table
```
public class BaseTable
extends java.lang.Object
implements Table, HasTableOperations, java.io.Serializable
```
Base Table implementation.
This can be extended by providing a TableOperations to the constructor.
Serializing and deserializing a BaseTable object returns a read only implementation of the BaseTable using a StaticTableOperations. This way no Catalog related calls are needed when reading the table data after deserialization.

public AppendFiles newFastAppend()
```
    Description copied from interface: Table
    
    Create a new append API to add files to this table and commit.
    Using this method signals to the underlying implementation that the append should not perform extra work in order to commit quickly. Fast appends are not recommended for normal writes because the fast commit may cause split planning to slow down over time.
    Implementations may not support fast appends, in which case this will return the same appender as Table.newAppend().

```
public ReplacePartitions newReplacePartitions()
```
    Description copied from interface: Table
