mongodb 建立索引提示异常：WiredTigerIndex::insert: key too large to index, failing 1483

MongoDB will not create an index on a collection if the index entry for an existing document exceeds the index key limit (1024 bytes). You can however create a hashed index or text index instead:

db.logcollection.ensureIndex({"Module":"hashed"})

db.logcollection.ensureIndex({"Module":"text"})

mongodb 对字段中有超过 1024 字节的不会建立索引，但是可以使用text 索引或者hashed 索引来实现。
