The MongoDB Connector for Apache Spark allows you to use MongoDB as a data source for Apache Spark. You can use the connector to read data from MongoDB and write it to Databricks using the Spark API. To make it even easier, MongoDB and Databricks recently announcedDatabricks Notebooks integ...
The Spark based MongoDB Migration tool is a JAR application that uses the Spark MongoDB Connector and the Azure Cosmos DB Spark Connector to read data from MongoDB and write data to VCore-based Azure Cosmos DB for MongoDB. It can be deployed in your Databricks cluster and virtual network, ...
your IoT solution sends commands to devices to control their behavior in near real time. Persistent connections maintain a network connection to the cloud and reconnect whenever there's a disruption. Use either the MQTT or the AMQP protocol for persistent device ...
spark.conf.set("spark.sql.streaming.stateStore.providerClass","com.databricks.sql.streaming.state.RocksDBStateStoreProvider") State rebalancing:As the state gets cached directly in the executors, the task scheduler prefers to send new micro-batches to where older micro-batches have gone,...
different ways of aggregating, custom roll-up, and more. Once the semantic data model is complete, users can query and drill down through a hierarchy in a consistent way. However, if you are dealing with complex data and massive volumes, it is not just enough to build a sema...
Data Lakes: Data lakes are designed to store structured, semi-structured, and unstructured data, providing a flexible and scalable solution. They retain raw data in its native format, facilitating extensive data ingestion and integration from various sources. This approach supports large volumes of di...
modes make it much simpler to shift to a lakehouse architecture: Connect live to massive volumes of data when conducting high throughput ad-hoc explorations and transition without disruption to in-memory access if an aggregated data set supporting a mission-critical dashboard needs massive concurre...
