DBFS provides support to reduce the expense of collecting DBFS Content API statistics.
DBFS Content API statistics are expensive to collect and maintain persistently. DBFS has support for buffering statistics in memory for a maximum of
flush_time centiseconds or a maximum of
flush_count operations, whichever limit is reached first), at which time the buffers are implicitly flushed to disk.
Clients can also explicitly invoke a flush using
flushStats. An implicit flush also occurs when statistics collection is disabled.
setStats is used to enable and disable statistics collection; the client can optionally control the flush settings by specifying non-
null values for the time and count parameters.
