What are the meanings of the different checkpoint/file config options and how would you suggest setting them?
There are 3 parameters related to persistence: CheckpointDir = directory CheckpointInterval = minutes checkpointWriteThreshold = One needs to specify a valid directory for “CheckpointDir” in order to support persistent spaces. The server will use this directory both to write a copy of the in-memory spaces and to write log records as each command is committed. If you have a failure, at restart the latest copy of a space will be read and these log records will be read and the copy of the space updated to the point of failure. The “CheckpointInterval” and “checkpointWriteThreshold” are used to determine how often a new copy of the space is made based on either time or number of updates. When a new copy of the space is made the log record is reset. So if you have a small space with lots of write and delete activity, the log file will grow rapidly and it is more efficient to checkpoint it regularly. However a large space with infrequent updates will generate a lot of overhead making frequen
