inline |
Create the specified collection in current collection space with options.
| [in] | pCollection | The collection name |
| [in] | options | The options are as following: ShardingKey : Assign the sharding key, foramt: { ShardingKey: { <key name>: <1/-1>} },
1 indicates positive order, -1 indicates reverse order.
e.g. { ShardingKey: { age: 1 } }
ShardingType : Assign the sharding type, default is "hash"
Partition : The number of partition, it is valid when ShardingType is "hash",
the range is [2^3, 2^20], default is 4096
ReplSize : Assign how many replica nodes need to be synchronized when a write
request (insert, update, etc) is executed, default is 1
Compressed : Whether to enable data compression, default is true
CompressionType : The compression type of data, could be "snappy" or "lzw", default is "lzw"
AutoSplit : Whether to enable the automatic partitioning, it is valid when ShardingType
is "hash", defalut is false
