ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields
Name | Description | |
---|---|---|
returnEnd |
Return the database key marking the end of the compaction operation
in a Btree or Recno database. This is generally the first key of the
page where the operation stopped.
| |
start |
If non-null, the starting point for compaction. For a Btree or
Recno database compaction will start at the smallest key greater
than or equal to the starting point. For a Hash database the
compaction will start in the bucket specified by the integer stored
in the starting point. If null, compaction will start at the
beginning of the database.
| |
stop |
If non-null, the stopping point for compaction. For a Btree or
Recno database compaction will stop at the page with the smallest
key greater than the stopping point. For a Hash database
compaction will stop in the bucked specified by the integer stored
in the stopping point. If null, compaction will stop at the
end of the database.
| |
TruncatePages |
If true, return pages to the filesystem when possible. If false,
pages emptied as a result of compaction will be placed on the free
list for re-use, but never returned to the filesystem.

Properties
Name | Description | |
---|---|---|
FillPercentage |
If non-zero, this provides the goal for filling pages, specified as
a percentage between 1 and 100. Any page not at or above this
percentage full will be considered for compaction. The default
behavior is to consider every page for compaction, regardless of its
page fill percentage.
| |
Pages |
If non-zero, compaction will complete after the specified number of
pages have been freed.
| |
Timeout |
If non-zero, and no Transaction is specified, this
parameter identifies the lock timeout used for implicit
transactions, in microseconds.
