> "User attributes" feature was added by IGNITE-12049, it was added to 2.9
> version, but for VER_2_8_0 condition:
> {code:java}
> if (ver.compareTo(VER_2_8_0) >= 0) {
> dataPageScanEnabled = nullableBooleanFromByte(reader.readByte());
> updateBatchSize = JdbcUtils.readNullableInteger(reader);
> userAttrs = reader.readMap();
> }
> {code}
> This breaks compatibility between 2.8 and 2.9 versions (both, backward and
> forward)
