This client is intended to be a simple GUI solution to work with cassandra 3.
What it already can:
- connect to cassandra
- load and show tables
- show table DDL
- show table data (simple editable table view with header)
- apply composite filters to loaded data
- execute query
Planned:
- lazy data load/pagination
- add/delete tables
- validation in filter values
- safe mode with manual commit-reset
- add/save connections
- select driver
- load driver files
- packaging
On selecting table data from context menu in table list all rows are loaded from cassandra
that is quite dangerous when having millions of entries in single table. Lazy loading and
pagination is planned but not implemented yet.
On cell edit updated row is immediately sent to cassandra - I'm planning to add safe mode
by executing DB queries only on commit button click with ability to reset all local uncommited
changes.
Type of cassandra column is respected. String value from filter is converted to same
type using cassandra driver codecs and column metadata. Filters are combined with
AND OR keywords and parentheses brackets.
