SymmetricDS: change operation from update to insert/delete in a table transformation

Question

on my source table i have a boolean column and if the boolean is switched on SymmetricDS should insert a row into my target table. If it was switched off it should the (eventually) inserted row from target table.

After reading the Documentation these operation change was not possible. Any hint how can i build a workaround with the existing capabilities?

my current setup (for an update at source it can only insert at target, not delete from FP_HIST)

insert into sym_trigger (TRIGGER_ID, SOURCE_SCHEMA_NAME, SOURCE_TABLE_NAME, CHANNEL_ID, CREATE_TIME, LAST_UPDATE_TIME
, SYNC_ON_INSERT, SYNC_ON_DELETE, SYNC_ON_UPDATE, SYNC_ON_UPDATE_CONDITION) 
VALUES ('eventattendee2fphist', 'webapps_base', 'eventattendee', 'channel_fphist', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP
, 0, 0, 1, 'new.attended AND new.id IN (select eat.id from webapps_base.eventattendee eat JOIN webapps_base.iacontact iac ON eat.fk_person_id = iac.fk_naturalperson_id AND NOT iac.lateregistration AND iac.access_path != ''FP_LATE_REGISTRATION'' JOIN webapps_base.event e ON e.id = eat.fk_event_id JOIN webapps_base.eventtypecatalog et ON et.id = e.fk_eventtypecatalog_id AND et.type = ''FP'' JOIN webapps_base.eventagencyassociations eag ON e.id = eag.fk_event_id JOIN webapps_base.agency ag ON ag.id = eag.fk_agency_id WHERE eat.attended)');

insert into SYM_TRIGGER_ROUTER (trigger_id, router_id, initial_load_order, create_time, LAST_UPDATE_TIME, ENABLED) 
values ('eventattendee2fphist', 'pg2ib', 1, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, 1);

insert into SYM_TRANSFORM_TABLE (
  transform_id, source_node_group_id, target_node_group_id, transform_point, SOURCE_SCHEMA_NAME, source_table_name,
  target_table_name, delete_action, transform_order, column_policy, update_first) 
values ('eventattendee2fphist', 'postgres', 'interbase', 'EXTRACT', 'webapps_base', 'eventattendee',
'FP_HIST', 'DEL_ROW', 1, 'SPECIFIED', 0);

insert into SYM_TRANSFORM_COLUMN (
  transform_id, include_on, target_column_name, source_column_name, pk,
  transform_type, transform_expression, transform_order) 
values ('eventattendee2fphist', '*', 'PVP', 'fk_Person_ID', 1, 'lookup', 'select ident FROM webapps_base.salespartner where fk_person_id = CAST(:fk_Person_ID AS BIGINT)', 1);


insert into SYM_TRANSFORM_COLUMN (

  transform_type, transform_expression, transform_order) 
values

insert into SYM_TRANSFORM_COLUMN (
  transform_id, include_on, target_column_name, source_column_name, pk,

values ('eventattendee2fphist', '*', 'DATUM', 'id', 0, 'lookup', 'select e.eventdate FROM webapps_base.eventattendee eat JOIN webapps_base.event e ON e.id = eat.fk_event_id WHERE eat.id = CAST(:id AS BIGINT)', 4);

Answer 1

it's possible now with my own enhancement to symmetricDS and my branch at github
