• isthmus: SubstraitToSql with Calcite's built-in dialects renders interval and LTZ casts their engines reject

• isthmus: CEIL, FLOOR and ROUND over a decimal emit an output type their declaration does not derive

  substrait-io/substrait-java#1349 · Filter by author nielspardon opened on Oct 1, 2026

• isthmus: visit(VirtualTableScan) decides between LogicalValues and VirtualTable over the columns a projection drops

  substrait-io/substrait-java#1345 · Filter by author nielspardon opened on Sep 30, 2026

• core: a read's projection mask validates none of its indices, so a malformed mask fails as a bare index exception or reads no columns

• isthmus: a SQL ROW column's NOT NULL fields become nullable when the column is nullable

  substrait-io/substrait-java#1341 · Filter by author nielspardon opened on Sep 29, 2026

• isthmus: Calcite's own type derivation still makes a nullable struct's fields nullable

  substrait-io/substrait-java#1339 · Filter by author nielspardon opened on Sep 29, 2026

• core: a field reference into a nullable struct, list or map derives a required type

  substrait-io/substrait-java#1338 · Filter by author nielspardon opened on Sep 29, 2026

• core: ExpressionCreator.precisionTimestamp(LocalDateTime) wraps a date outside the nanosecond range into a different instant

  substrait-io/substrait-java#1337 · Filter by author nielspardon opened on Sep 29, 2026

• isthmus: update targets round-trip through column names, so duplicate or differently cased names change which column is updated

  substrait-io/substrait-java#1336 · Filter by author nielspardon opened on Sep 29, 2026

• spark: a write's table schema pairs top-level column names with a nested struct, so its NamedStruct is malformed in both directions

  substrait-io/substrait-java#1335 · Filter by author nielspardon opened on Sep 29, 2026

• core: nothing bounds an update's column_target, and SubstraitBuilder.namedUpdate builds a table schema that contradicts it

  substrait-io/substrait-java#1334 · Filter by author nielspardon opened on Sep 29, 2026

• isthmus: visit(NamedUpdate) builds a TableModify whose input lacks the source-expression columns, so SubstraitToSql renders SET A = * or throws

  substrait-io/substrait-java#1333 · Filter by author nielspardon opened on Sep 29, 2026

• isthmus: visit(NamedUpdate) declares a transformation's correlation on the filter below the TableModify that uses it

  substrait-io/substrait-java#1332 · Filter by author nielspardon opened on Sep 29, 2026

• isthmus: visit(NamedUpdate) lets RelBuilder fold away a constant condition, so "update no rows" round-trips to "update every row"

  substrait-io/substrait-java#1331 · Filter by author nielspardon opened on Sep 29, 2026

• core: return-type derivation cannot read integer_parameter from a value argument, so strptime_* and assume_timezone precision returns are not derivable

• isthmus-cli: the README's extended-expression examples show outputNames ["new-column"] but the CLI emits ["column-1"]

• isthmus: a ROWS window offset that is not an integral literal is emitted without the required int64 type

• isthmus: a negative or zero interval RANGE window offset is emitted unnormalized

• core: an unspaced '-' before a digit lexes as a negative literal, so decimal<P-1, 0> does not parse
