cbft-bleve-dump

The cbft-bleve-dump utility allows you to print all the rows in the specified index. This is helpful for troubleshooting because the index or index fragments can be examined without access to the Couchbase Server.

The parameter -index is required (not optional) and it specifies the path to the index to dump. The remaining parameters describe special modes and are optional.

Table 1. cbft-bleve-dump parameters
Parameters	Description
`-index`	Required. Specifies the path to the index to dump.
`-dictionary`	Optional. Prints the term dictionary for the specified field.
`-docID`	Optional. Print all the rows pertaining to the single specified document.
`-fields`	Optional. Print the field names and field ids in the index.
`-mapping`	Optional. Print a JSON serialization of the index mapping.

If none of these alternate modes have been specified it will dump all rows in the index.

Permission Required

This command line tool only accesses data via the file system. Ensure that you have the appropriate permissions from the host OS.
