public ArangoSearchCreateOptions consolidationIntervalMsec(Long consolidationIntervalMsec)
consolidationIntervalMsec - Wait at least this many milliseconds between committing index data changes
and making them visible to
queries (default: 60000, to disable use: 0). For the case where there are a
lot of inserts/updates, a
lower value, until commit, will cause the index not to account for them and
memory usage would
continue to grow. For the case where there are a few inserts/updates, a
higher value will impact
performance and waste disk space for each commit call without any added
benefits.public ArangoSearchCreateOptions commitIntervalMsec(Long commitIntervalMsec)
commitIntervalMsec - Wait at least this many milliseconds between committing view data store changes and
making documents visible to
queries (default: 1000, to disable use: 0). For the case where there are a lot of
inserts/updates, a lower value,
until commit, will cause the index not to account for them and memory usage would
continue to grow. For the case
where there are a few inserts/updates, a higher value will impact performance and
waste disk space for each
commit call without any added benefits. Background: For data retrieval ArangoSearch
views follow the concept of
“eventually-consistent”, i.e. eventually all the data in ArangoDB will be matched by
corresponding query
expressions. The concept of ArangoSearch view “commit” operation is introduced to
control the upper-bound on the
time until document addition/removals are actually reflected by corresponding query
expressions. Once a “commit”
operation is complete all documents added/removed prior to the start of the “commit”
operation will be reflected
by queries invoked in subsequent ArangoDB transactions, in-progress ArangoDB
transactions will still continue to
return a repeatable-read state.public ArangoSearchCreateOptions cleanupIntervalStep(Long cleanupIntervalStep)
cleanupIntervalStep - Wait at least this many commits between removing unused files in data directory
(default: 10, to
disable use: 0). For the case where the consolidation policies merge segments often
(i.e. a lot of
commit+consolidate), a lower value will cause a lot of disk space to be wasted. For
the case where the
consolidation policies rarely merge segments (i.e. few inserts/deletes), a higher
value will impact
performance without any added benefits.public ArangoSearchCreateOptions consolidationPolicy(ConsolidationPolicy consolidationPolicy)
