ArangoDB 3.1.10发布，高性能NoSQL数据库

ArangoDB 3.1.10 发布了，Arangodb 是一个开源数据库，具有用于文档，图形和键值的灵活数据模型。同时也是一个高性能数据库，使用类似 SQL 的查询语言或 JavaScript 扩展构建高性能应用。

更新内容：

joi： 8.4.2 to 9.2.0

joi-to-json-schema： 2.2.0 to 2.3.0

sinon：1.17.4 to 1.17.6

lodash： 4.13.1 to 4.16.6

2、新增

added shortcut for AQL ternary operator instead of `condition ? true-part : false-part` it is now possible to also use a shortcut variant `condition ? : false-part`, e.g.

added --replication-factor, --number-of-shards and --wait-for-sync to arangobench

added optional detail flag for db..count() setting the flag to `true` will make the count operation returned the per-shard counts for the collection:

db._create("test", { numberOfShards: 10 });
for (i = 0; i < 1000; ++i) {
db.test.insert({value: i});
}
db.test.count(true);

{
"s100058" : 99,
"s100057" : 103,
"s100056" : 100,
"s100050" : 94,
"s100055" : 90,
"s100054" : 122,
"s100051" : 109,
"s100059" : 99,
"s100053" : 95,
"s100052" : 89
}

added optional memory limit for AQL queries:db._query("FOR i IN 1..100000 SORT i RETURN i", {}, { options: { memoryLimit: 100000 } });

added server startup option `--query.memory-limit`

added convenience function to create vertex-centric indexes.

added option -D to define a configuration file environment key=value

3、修复和改进

fixed wrong sorting order in cluster, if an index was used to sort with many shards.

turn on UTF-8 string validation for VelocyPack values received via VST connections

change default log output for tools to stdout (instead of stderr)

changed encoding behavior for URLs encoded in the C++ code of ArangoDB

Foxx request URL suffix is no longer unescaped

@arangodb/request option json now defaults to `true` if the response body is not empty and encoding is not explicitly set to `null` (binary).

Foxx configuration values for unknown options will be discarded when saving the configuration in production mode using the web interface

module.context.dependencies is now immutable

process.stdout.isTTY now returns `true` in arangosh and when running arangod with the `--console` flag
