See Also:

Constant Field Values

DEFAULT_NUMBER_TOTAL_REPS_REQUIRED_DELETE

public static final int DEFAULT_NUMBER_TOTAL_REPS_REQUIRED_DELETE

The default value for config option that specified the number of replications required for a chunk to be deleted.

A chunk will only be deleted if it is out of its hash span and there are enough copies on the network (specified by this variable). Furthermore, there must also be enough copies in the appropriate hash span, which is specified in DEFAULT_NUMBER_TOTAL_REPS_IN_HASH_SPAN_REQUIRED_DELETE

See Also:

Constant Field Values

DEFAULT_NUMBER_TOTAL_REPS_IN_HASH_SPAN_REQUIRED_DELETE

public static final int DEFAULT_NUMBER_TOTAL_REPS_IN_HASH_SPAN_REQUIRED_DELETE

The default value for config option that specifies the number of replications that are in the correct hash span (i.e., how many other servers have this chunk right now that have the chunk's hash in their hash span).

A chunk will only be deleted if it is out of its hash span and there are enough total copies on the network (see DEFAULT_NUMBER_TOTAL_REPS_REQUIRED_DELETE), along with enough copies in the appropriate hash span.

See Also:

Constant Field Values

DEFAULT_SHOULD_HEALING_THREAD_BALANCE_DATA_BLOCKS

public static final boolean DEFAULT_SHOULD_HEALING_THREAD_BALANCE_DATA_BLOCKS

Should the healing thread bother balancing the data blocks? This is the default value.

DEFAULT_REQUIRED_PERCENTAGE_DIFFERENCE_TO_BALANCE_DATA_DIRECTORIES

public static final double DEFAULT_REQUIRED_PERCENTAGE_DIFFERENCE_TO_BALANCE_DATA_DIRECTORIES

The required difference in percentage between the data directories with least and most available space before transfering.

This only matters if healing thread is set to auto balance.

Note that host the calculation is determined:

1. Find data directory with most available space: Must have at least 1GB of space available (the size of 10 full DataBlock's). Calculate percentage of its available space is used.
2. Find data directory with least available space: Calculate percentage of its available space is used. Must meet user-defined minimum used percentage of its space.
3. Subtract the percentage difference of the least from the most: if difference meets required minimum difference, the data will be moved from one to the other.

Note should always be a positive value less than 100.00. Anything else will be ignored by healing thread.

See Also:

Constant Field Values

DEFAULT_REQUIRED_PERCENTAGE_FOR_MOST_USED_DATA_DIRECTORY_BEFORE_BALANCE

public static final double DEFAULT_REQUIRED_PERCENTAGE_FOR_MOST_USED_DATA_DIRECTORY_BEFORE_BALANCE

The minimum percentage of its available space used by a data directory before it will be a candidate for balancing. This sets a threshold before data will be moved away toward other data blocks.

This only matters if healing thread is set to auto balance.

Note that this does not guarentee that data will be moved to other data directories. Three additional criteria must be met:

• Balancing must be allowed
• Another data directory must have at least 1GB free space and
• the same data directory above must have a percentage difference with the candidate data directory that exceeds the minimum percentage difference rule.

Note should always be a positive value less than 100.00. Anything else will be ignored by healing thread.
