Example Configuration & Output
Example ledger configuration files are provided here. These use the Chinook sample
database. Here's an SQLite version.
Files
-
chinook.conf - Main configuration file used
by the sldg tool.
This properties file (you can name it whatever), specifies 2 SQL queries, one defining the composition
of a row for a given row number, the other, defining how many rows there are. It also specifies the
location of 3 tables for tracking the row hashes (less than a 100 bytes overhead per row).
-
meta/chinook_info.json - Optional
ledger info file. This describes the ledger, its name, its column names, column value types,
column descriptions, etc. If present (and well formed), then sldg can embed it in
the morsel files it generates. The location of this file can be set relatively to absolutely.
Here, the
chinook.conf file references it relatively.
-
meta/report/queryTotal.json - Optional
report template. This is a toy example of the template (lifted from unit tests), illustrating
some of the DSL's capabilities (see next). Note this uses the image asset
report/images/example_icon.png.
-
chinook-800-830-r.mrsl - Morsel file
generated by the sldg using the configuration above.
-
report.pdf - Toy report generated by the
mrsl tool from the above morsel file.
