Does it need to sync like this everytime I connect to Calibre? I mean Does it do partial sync or full sync everytime it connects as a device?
thanks

CC syncs all metadata whenever you connect as a wireless device. CC "syncs" book files (downloads changes) whenever you use the Wireless Device/Sync books option.
CC's metadata syncs usually take a small number of seconds. Calibre and CC both cache the data. CC asks calibre what has changed and downloads only that metadata. However ...
Given your other post that says you are using some other method to transfer books, my guess is that you are also triggering book scanning. This optional CC process (defaults to On) checks on every wireless connect for books that are in CC's folders but are not in CC's database. For each such book it sends information to calibre in hopes that calibre can match it to some book in the library. For epubs, CC extracts the metadata from the book and send that. For all other formats (mobi, pdf, etc) CC sends the *entire* book file to calibre. This can take a very long time.
You can try turning off the scan to see if the metadata sync runs faster. The option is in CC / Settings / Connecting to calibre / Wireless device connection / Scan on connect.
Another possibility is that the calibre metadata cache is disappearing from the computer running calibre. I don't know why this might be happening, but if it does then CC must upload all the metadata from its library to calibre.
BTW: we recommend that people do not use non-CC connections to put books into CC's book directory. As I think you have discovered, down that road lies perdition. You might consider running CC's "Books with missing files" command to see if the book file names have been changed from what CC expects (three-dot menu / Books with missing files).
