Capitalware is ready for beta testers for a new solution called: MQ Message Compression (MQMC). MQMC is an MQ API Exit.
Question: Would you trade a little CPU time to drastically reduce the disk I/O time?
I have written a long blog posting on the internals of queue manager logging (with help from Chris Frank) and why you might want to use message compression to speed up message processing time.
The MQMC supports the following 8 lossless compression algorithms:
- LZ1 (aka LZ77) – I used Andy Herbert’s modified version with a pointer length bit-width of 5.
- LZ4 – It is promoted as extremely fast (which it is).
- LZW – I used Michael Dipperstein’s implementation of Lempel-Ziv-Welch.
- LZMA Fast – I used the LZMA SDK from 7-Zip with a Level set to 4.
- LZMA Best – I used the LZMA SDK from 7-Zip with a Level set to 5.
- RLE – Run Length Encoding – I wrote the code from pseudo code – very basic stuff.
- ZLIB Fast – I used Rich Geldreich’s miniz implementation of ZLIB with a Level of Z_BEST_SPEED.
- ZLIB Best – I used Rich Geldreich’s miniz implementation of ZLIB with a Level of Z_BEST_COMPRESSION.
I plan on building MQMC for AIX, HP-UX, IBM i (OS/400), Linux (x86, x86_64, POWER & zSystem), Solaris (SPARC & x86_64) and Windows. MQMC will support IBM MQ v7.1, v7.5, v8.0, v9.0, v9.1 and v9.2.
Beta testing MQ Message Compression is absolutely free including support (no strings attached).
If you interesting in trying it out, please send an email to support@capitalware.com to request a trial of MQ Message Compression.
