Some features of MongoDB Tool

MongoDB can be used as a file system with load balancing and data replication features over multiple machines for storing files. Following are the main features of MongoDB.

  • Ad hoc queries
  • Indexing
  • Replication
  • Load balancing
  • Aggregation
  • Server-side JavaScript execution
  • Capped collections

Hive

Apache Hive is a data warehouse infrastructure built on top of Hadoop for providing data summarization, query, and analysis. Hive gives an SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop.

How it Works:

Hive has three main functions data summarization, query and analysis.It supports queries expressed in a language called HiveQL, which automatically translates SQL-like queries into MapReduce jobs executed on Hadoop.

Features of Apache Hive

Apache Hive supports analysis of large datasets stored in Hadoop’s HDFS and compatible file systems such as Amazon S3 file system. Other features of Hive include:

  • Index type including compaction and Bitmap index as of 0.10
  • Variety of storage types such as plain text, RCFile, HBase, ORC, and others
  • Operating on algorithms including DEFLATE, BWT, snappy, etc.

Sqoop

Sqoop (SQL-to-Hadoop) is a big data tool that offers the capability to extract data from non-Hadoop data stores, transform the data into a form usable by Hadoop, and then load the data into HDFS

How it Works

Sqoop got the name from SQL + Hadoop. It supports incremental loads of a single table or a free form SQL query as well as saved jobs which can be run multiple times to import updates made to a database since the last import.

Here are some important and usable features of Sqoop

  • Parallel import/export
  • Import results of SQL query
  • Connectors for all major RDBMS Databases
  • Kerberos Security Integration
  • Support for Accumulate
