Stanislav and I have been working on a SQL based EntityStore lately. The
SQLEntityStore is working on Apache Derby and PostgreSQL for now.
What approach have you taken: split up entity
props/assocs/manyassocs into columns, or dump blob into key-blob
table?
The EntityStore use a single table with three columns: entity_pk,
entity_identity and entity_state.
And the indexing generates a single table for each qualified-name. The
structure of the table depends on what type it is - property
(normal/collection/valuecomposite), asso, or multi-asso. Additionally
it has a few fixed meta-information tables, and similar-kind of table
as with ES. Currently we are working on synergy between SQL ES and SQL
Indexing - mostly by making same entity appear with same entity_pk in
both.
