The json2sstable utility
Converts a JSON representation of a table (aka column family) to a Cassandra usable SSTable format.
Converts a JSON representation of a table (aka column family) to a Cassandra usable SSTable format.
Note: This tool is not recommended as a production tool and is not suitable for
production operations!
Note: Starting with version 0.7, json2sstable and sstable2json
must be run so that the schema can be loaded from system tables. This means that the
cassandra.yaml file must be in the classpath and refer to
valid storage directories. For more information, see the Import/Export section of
http://wiki.apache.org/cassandra/Operations.
Procedure
Usage:
bin/json2sstable -K KEYSPACE -c COLUMN_FAMILY JSON SSTABLE
JSON should be a path to the JSON file.
SSTABLE should be a full path to a {table-name}-Data.db file in Cassandra’s data directory. For example, /var/lib/cassandra/data/Keyspace1/Standard1-e-1-Data.db.
