Highlights

RedisGraph 2.10 introduces new path algorithms, additional expressivity (constructs and functions), performance improvements, and bug fixes.

What's new in 2.10

• New pathfinding algorithms:
  • The algo.SPpaths procedure yields one, n, or all minimal-weight, optionally bounded-cost, optionally bounded-length paths between a given pair of nodes.
  • The algo.SSpaths procedure yields one, n, or all minimal-weight, optionally bounded-cost, optionally bounded-length paths from a given node.
• Introduce SET for adding node labels and REMOVE for removing node labels, node properties, and edge properties.
• Support deleting paths with DELETE.
• Introduce 29 functions: toBoolean, toBooleanOrNull, toFloatOrNull, toIntegerOrNull, toStringOrNull, toBooleanList, toFloatList, toIntegerList, toStringList, properties, split, last, isEmpty, e, exp, log, log10, sin, cos, tan, cot, asin, acos, atan, atan2, degrees, radians, pi, and haversin.
• Graph slow log can be reset with GRAPH.SLOWLOG g RESET.
• Queries are now atomic (Atomicity is the guarantee that each query either succeeds or fails with no side effects). Whenever a failure occurs, the query effect is rolled back from an undo log.

Details

• Bug fixes (since 2.10-RC1):

  • #2695 Potential crash on certain write queries (MOD-4286, MOD-4545)
  • #2724 Potential crash when setting property values based on nonexistent properties
  • #2460, #2637, #2680 Crash on invalid queries
  • #2672 Wrong matching result on multiple labels
  • #2643 Duplicate reports when matching relationship type :R|R
  • #2687, #2414 Error when UNWINDing relationships
  • #2636 MERGE ... ON ... - cannot remove property by setting it to null
  • #2710 Undo log fix
  • #2435 Incorrect result when comparing a value to NaN
  • #2497 Incorrect result when comparing a value to null
  • #2676 sqrt, log, log10 - incorrect result for negative values
  • #2213 Division and Modulo by zero - wrong behavior
