File name (FILENAME) |
The absolute or relative path to
the folder where log store files are written. A relative path is
preferred. The filename property only creates
the directory for the last level specified. For example, if the
property is set to C:\dir1\dir2\dir3, the
dynamic.log file will be located in
C:\dir1\dir2\dir3, provided that
C:\dir1\dir2\ already exists and the
ESP project has permissions to
create dir3. If
C:\dir1\dir2\ or permissions do not exist,
ESP generates a runtime error and
the project stops running. |
Max Size (GB) (MAXFILESIZE) |
The maximum size of the log store
file in MB. Default is 8MB. |
Sweep Amount (%)
(SWEEPAMOUNT) |
The amount of data, in megabytes,
that can be cleaned in a single pass. Default is 20 percent of
maxfilesize. |
Reserve Percentage (%)
(RESERVEPCT) |
The percentage of the log to keep
as free space. Default is 20 percent. |
Ck Count (CKCOUNT) |
The maximum number of records
written before writing the intermediate metadata. Default is
10,000. |
Sync (SYNC) |
Specifies whether the persisted
data is updated synchronously with every stream being updated. A value
of true guarantees that every record acknowledged by the system is
persisted at the expense of performance. A value of false improves
performance, but it may result in a loss of data that is acknowledged,
but not yet persisted. Default is false. |
