Class Mutation

All Implemented Interfaces:

Direct Known Subclasses:
ConditionalMutation

public class Mutation extends Object implements org.apache.hadoop.io.Writable
Mutation represents an action that manipulates a row in a table. A mutation holds a list of column/value pairs that represent an atomic set of modifications to make to a row.

Convenience methods which takes columns and value as CharSequence (String implements CharSequence) are provided. CharSequence is converted to UTF-8 by constructing a new Text object.

When always passing in the same data as a CharSequence/String, it's probably more efficient to call the Text put methods. This way the data is only encoded once and only one Text object is created.

All of the put methods append data to the mutation; they do not overwrite anything that was previously put. The mutation holds a list of all columns/values that were put into it.

The putDelete() methods do not remove something that was previously added to the mutation; rather, they indicate that Accumulo should insert a delete marker for that row column. A delete marker effectively hides entries for that row column with a timestamp earlier than the marker's. (The hidden data is eventually removed during Accumulo garbage collection.)

This class has many overloaded put and putDelete methods. These were added to support different subset of fields and types. The functionality of all of these put methods and more is provided by the new fluent at() method added in 2.0.

    • at

      Fluent API for putting or deleting to a Mutation that makes it easy use different types (i.e byte[], CharSequence, etc) when specifying the family, qualifier, value, etc.

      Methods are optional but must follow this order: family, qualifier, visibility, timestamp.

      The put and delete methods end the chain and add the modification to the Mutation.

      The following is an example if using at() to put and delete. Notice how the example mixes String and byte[].

       
         Mutation m = new Mutation("row0017");
         m.at().family("001").qualifier(new byte[] {0,1}).put("v99");
         m.at().family("002").qualifier(new byte[] {0,1}).delete();
       
       
      Returns:
