This is a maintenance release for RedisGraph 2.10

Update urgency: HIGH: There is a critical bug that may affect a subset of users. Upgrade!

Details

Bug fixes:

• #2754 Partial sync may hang (MOD-4594)

Improvements:

• #2757 Improved performance of indegree and outdegree
• #2681 Fixed some error messages
• #2740 Don’t show partial results for timed-out GRAPH.PROFILE

This is the General Availability release of RedisGraph 2.10

Headlines:

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

What's new in 2.10

• New path-finding 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

Notes:

• The version inside Redis will be 2.10.4 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a GA flag.
• Minimal Redis version: 6.2
• License update: see LICENSE.txt

This is the first Release Candidate of RedisGraph 2.10

Details

Features (since 2.10-M01):

• Introduce SET for adding node labels and REMOVE for removing node labels, node properties, and edge properties.
• Support deleting paths with DELETE.
• Introduce 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 functions.
• Graph slow log can be reset with GRAPH.SLOWLOG g RESET (also added in 2.8.20).

Performance enhancements (since 2.10-M01):

• #2519 When a query is cached and then a relevant index is created - recalculate the execution plan (also added in 2.8.19)

Bug Fixes (since 2.10-M01):

• #2635 Cannot UNWIND an expression that is not a list
• #2484 Indexes can be created on invalid property names
• #2523, #2532, #2589, #2622 Undo-log fixes
• #2591 Potential crash trying to utilize a nonexistent index (also fixed in 2.8.20)
• #2558 Multi-relationship properties created before index creation are not indexed (also fixed in 2.8.20)
• #2571 min and max return wrong results when the argument is an array (also fixed in 2.8.20)
• #2587 Some queries generate a "forced unlocking commit flow" warning (also fixed in 2.8.20)
• #2517 Crash on invalid REDUCE queries (also fixed in 2.8.19)
• #2525 toJSON - node labels are not separated with ',' (also fixed in 2.8.19)
• #2467 Possibly wrong results when using a variable named 'anon_N' (also fixed in 2.8.19)
• #2522 Deleting an edge index leaves traces (also fixed in 2.8.19)
• #2477 Cannot extract the latitude or the longitude of a point (also fixed in 2.8.19)

Notes:

• The version inside Redis will be 2.10.2 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a Release Candidate flag. The GA version will follow soon.
• Minimal Redis version: 6.2
