This custom deserializer makes it easy to process files in hive without any pre-processing.\n\nSimply install the DynamoDbSerDe jar and specify the row format as the DynamoDB SerDe in your queries. Pick the DynamoDb column names you want to access and a type they should be. Per line of data the DynamoDb SerDe will locate the columns you specified and coerce the values into the types you specify.\n\nExample query:\n```sql\nADD jar /path/to/jar/dynamodb-hive-serde-1.0-SNAPSHOT.jar;\n\nCREATE EXTERNAL TABLE dynamodb (id string, updated_at string, created_at string, version int)\nROW FORMAT SERDE 'com.lyft.hive.serde.DynamoDbSerDe'\nLOCATION '/dynamodb/input/';\n```\n\n## Timestamp format\nYou can specify a custom time format, which will be used to construct a [Joda Time DateTimeFormatter](http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html). For example:\n```sql\nCREATE EXTERNAL TABLE dynamodb (id string, updated_at timestamp, created_at timestamp, version int)\nROW FORMAT SERDE 'com.lyft.hive.serde.DynamoDbSerDe'\nWITH SERDEPROPERTIES ('input.timestamp.format'='yyyy-MM-dd\\'T\\'HH:mm:ss.SSSSSSZ')\nLOCATION '/dynamodb/input/';\n```\n\n## Building\nFirst, install maven, then:\n```\nmvn package\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flyft%2Fdynamodb-hive-serde","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flyft%2Fdynamodb-hive-serde","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flyft%2Fdynamodb-hive-serde/lists"}
