Serde in hive<\/h2>\n

\n
• Apache\u00a0Hive<\/b>\u00a0uses\u00a0Serde\u00a0<\/b>to read and write data from tables.<\/li>\n
• A SerDe is a short name for a Serializer Deserializer.<\/li>\n
• An important concept behind\u00a0Hive<\/b>\u00a0is that it DOES NOT own the Hadoop File System (HDFS) format that data is stored in.<\/li>\n
• Apache Hive SerDe.deserialize() used to select the data;when method is called and inserting the data SerDe.serialize() method is called.<\/li>\n
• It uses the SerDe interface for IO.<\/li>\n
• In SerDe interface handles both serialization and deserialization and also interpreting the results of serialization as individual fields for processing.<\/li>\n
• It allows Hive to read data from a table, and write it back to HDFS in any format, user can write data formats.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
