[Aerospike Connect for Spark version 2.8.0](https://www.aerospike.com/enterprise/download/connectors/aerospike-spark/notes.html#2.8.0)was released on July 14, 2021.

- Supported until October 14, 2022.
- Tested with Apache Spark 2.4.7, Scala 2.11.12, & Python 3.7.
- Minimum supported Aerospike Server version 5.0.

#### New Features

- [CONNECTOR-166] - Support batchget queries with digests in Spark Connector.
- [CONNECTOR-142] - Data Sampling using the Spark Connector using [`aerospike.sample.size`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-related-to-performance) flag.
- [CONNECTOR-142] - Support boolean bins in the Spark Connector (refer to [`aerospike.booleanbin`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-that-are-optional) in the documentation).
- [CONNECTOR-211] - Support partial updates of records using the [`aerospike.update.partial`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-that-are-optional) flag.

#### Improvements

- Migrated from queryPartiton() call to ScanPartitions().
- Updated Spark version to 2.4.7.
- Update Client version to 5.1.5.
- Migrated to Expressions for scans.
- Pushdown support for Float & Double datatypes.

#### Bug Fixes

- [CONNECTOR-205] - Filter out records that breach write block size in Aerospike via Spark Connector.
- [CONNECTOR-212] - Handle nulls in full record writes (REPLACE, REPLACE\_ONLY, and CREATE\_ONLY).
- [CONNECTOR-215] - Writes are slower in the Spark Connector v2 version. Introduced a new flag [`aerospike.write.batchsize`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-related-to-performance) to control write throughput.

#### Known Issues

- DataSource v2 API does not support the SQL statement `INSERT INTO` a temp view. Use DataFrame syntax for equivalent functionality.
- [`aerospike.write.mode`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-that-are-optional) flag overrides Apache Spark write mode.
- Spark connector stores spark DateType and TimestampType as long. In Aerojoin API calls convert these types to long.
- [CONNECTOR-312] - Update spark connectors with latest java clients to address CLIENT-1637 (“partition unavailable” errors occur). **Fixed in version [2.8.1](https://download.aerospike.com/enterprise/download/connectors/aerospike-spark/notes.html#2.8.1)**.

#### Updates

- The default value of flag [`aerospike.partition.factor`](https://docs.aerospike.com/docs/connect/processing/spark/configuration.html#properties-related-to-performance) has changed from 12 to 8. Please update your application accordingly.
