esProc connects to databases via ODBC or JDBC. But it also provides Search External Library functionality in case a database to be connected doesn’t support JDBC and ODBC connectivity.

 

A variety of external libraries - AlicloudCli, ElasticsearchCli, HiveCli, SparkCli, HbaseCli, RedisCli, DatastaxCli, Report5Cli, ExcelCli, HdfsFileCli, OlapCli, WebserviceCli, FtpCli, SapCli, MongodbCli, KafkaCli, InformixCli, ZipCli, YimmingCli and Webcrawl - are embedded in the esProc installation package to access Alicloud, elasticsearch, Hive databases, Spark systems, HBase databases, Redis databases, Cassandra databases, Informix databases, report files, Excel files, HDFS file systems, multidimensional databases, web services, FTP file systems, SAP systems, Kafka platform, MongoDB databases, Zip files, YiMing AI Model service and web indexing service. There are two steps for using these external libraries.
