A maintenance release for ArangoDB 2.2 is available. It will fix the performance problems encountered with the new graph module plus
v2.2.1 (2014-07-24)
-------------------
* fixed issue with --check-version: when creating a new database the check failed
* issue #947 Foxx applicationContext missing some properties
* added startup option `--wal.suppress-shape-information`
Setting this option to `true` will reduce memory and disk space usage and require
less CPU time when modifying documents or edges. It should therefore be turned on
for standalone ArangoDB servers. However, for servers that are used as replication
masters, setting this option to `true` will effectively disable the usage of the
write-ahead log for replication, so it should be set to `false` for any replication
master servers.
The default value for this option is `false`.
* added optional `ttl` attribute to specify result cursor expiration for HTTP API method
`POST /_api/cursor`
The `ttl` attribute can be used to prevent cursor results from timing out too early.
* (reported by Christian Neubauer):
The problem was that in Google's V8, signed and unsigned chars are not always declared cleanly.
so we need to force v8 to compile with forced signed chars which is done by the Flag:
-fsigned-char
at least it is enough to follow the instructions of compiling arango on rasperry
and add "CFLAGS='-fsigned-char'" to the make command of V8 and remove the armv7=0
* Fixed a bug with the replication client. In the case of single document
transactions the collection was not write locked.
