src_databases

src_schemas

Returns a character vector containing the names of all the
 available databases, in alphabetical order, including the
 <code>_impala_builtins</code> database.

'SQL' back-end to 'dplyr' for Apache Impala, the massively
parallel processing query engine for Apache 'Hadoop'. Impala enables
low-latency 'SQL' queries on data stored in the 'Hadoop' Distributed
File System '(HDFS)', Apache 'HBase', Apache 'Kudu', Amazon Simple
Storage Service '(S3)', Microsoft Azure Data Lake Store '(ADLS)',
and Dell 'EMC' 'Isilon'. See <https://impala.apache.org> for more
information about Impala.
